About this RSO gummies recipe

Editorial update: October 5, 2026. We clarified the recipe notes and storage wording. This update does not represent a new kitchen test.

This RSO gummies guide includes the recipe, an equipment list, ingredient notes and answers to frequently asked questions.

If you’ve made Infused Gummy Bears with “canna-oil” or cannabutter in the past, you may have been disappointed by the taste and texture.

My favorite texture and taste come from using RSO to infuse gummies.

Using Full Extract Cannabis Oil, also known as FECO or Rick Simpson Oil, which is RSO is the perfect way make stronger THC gummies as well.

You’ll see these acronyms used interchangeably, although the process of making them may differ.

Another pitfall of home cannabis-infused recipes is that your infused THC gummy bears will begin to mold if left at room temperature or if stored for too long in the refrigerator.

Ingredients You’ll Need to Make THC Infused Gummies

Let’s look at the individual ingredients needed for cannabis infused Gummies and define some of the less common ones.

Bulk Unflavored Knox Gelatin:

This is a clear, odorless protein derived from collagen found in animal bones, hides, and tissues.

It’s responsible for giving gummies their chewy, jelly-like consistency.

Jello Flavor:

A popular gelatin dessert, it introduces both flavor and color to the recipe.

Available in a variety of flavors, it allows for customization of the final gummy taste.

Corn Syrup:

A sweet syrup derived from cornstarch, it provides sweetness, enhances the gummy’s texture, and prevents sugar crystallization.

LorAnn Oil Flavoring:

Highly concentrated, these are used to intensify or introduce additional flavors that complement the base Jello flavor.

You may use food-grade citrus essential oils instead. Essential oils are much stronger, though. I start with about 10 drops. I use the Vitality Dietary Culinary Oils from Young Living. (white labeled)

Sunflower Lecithin:

A fatty substance extracted from sunflower seeds, it acts as an emulsifier.

It helps ingredients mix well together, especially in recipes where oil-based and water-based components are combined.

According to WebMD, “Lecithin is a mixture of fats that are essential to cells in the human body. It can be found in many foods, including soybeans and egg yolks.” 

My go-to choice is the liquid lecithin sourced from sunflowers.

Some people steer clear of the soy-based lecithin due to allergy concerns.

The author identifies liquid sunflower lecithin as her preferred form. A one-for-one substitution with granules has not been verified in this update.

Food Grade Glycerin:

A clear, odorless liquid, glycerin is sweet-tasting and viscous.

It helps with texture and can act as a solvent for certain ingredients.

As a beginner, I would use a neutral oil such as MCT oil as a carrier to dissolve FECO and RSO in to, but I found glycerin to be far superior.

In addition, the added sweetness helps hide the unwanted taste of the cannabis. 

RSO or Feco Syringe:

RSO (Rick Simpson Oil) or FECO (Full Extract Cannabis Oil) is a concentrated form of cannabis.

It contains a full profile of cannabinoids and can be sourced in various potencies and cannabinoid ratios. (Full-Spectrum)

Potassium Sorbate as a Mold Preventative:

This ingredient has become indispensable for me, especially when it comes to enhancing the longevity of my gummies.

You can easily find it at a reasonable price from candy-making suppliers like LorAnn.

(I’ve included the exact one I use in the equipment links.)

Foods like cheese, yogurt, and dried fruits typically contain potassium sorbate not just for its preservation qualities but also for its neutral taste, which avoids leaving a lingering aftertaste.

Wondering how much LorAnn Mold Inhibitor (Potassium Sorbate) to use in gummies?

It’s essential to know the weight of your batch, which can vary based on your infusion method and mold size.

This recipe could yield anywhere between 95 to 140 pieces!

For more precision in determining the necessary quantity, consider the average weight of your completed batches.

The guideline from LorAnn Oils suggests 2 tsp for every 5 lbs of the total batch.

Take, for instance, a store-bought 10-ounce bag of Haribo gummies, which contains roughly 120 bears.

Based on this, I deduced that this recipe would require about ¼ tsp of the mold inhibitor.

Here’s a breakdown of LorAnn Oils Mold Inhibitor measurements:

• 2 tsp for every 5 lbs or 80 ounces
• 1 tsp for 40 ounces
• ½ tsp for 20 ounces
• ¼ tsp for 10 ounces
• ⅛ tsp for 5 ounces.

Follow the manufacturer’s current directions for this ingredient. Its inclusion does not validate the shelf life of this recipe. 

How to Add RSO to Any Gummy Bear Recipe

Combine and warm:

⅛-¼  cup Glycerin or you can use additional corn syrup or honey in a pinch

1 tsp Sunflower or Soy Lecithin ( liquid or granules) 

Add the desired amount of concentrated Full Extract Cannabis Oil (FECO/RSO). Choose THC, CBD, or any cannabinoid your dispensary offers. You can make your own combinations or ratios! 

I mix these ingredients with a glass or metal measuring cup on an electric mug warmer. Heat and stir often until the mixture is well combined.

Do not boil. If you don’t have one of these handy warmers, you’ll need a very small saucepan and stir the mixture constantly until you’re satisfied.

I prefer to heat these ingredients separately to limit my cannabis from extra heat, and this step helps to emulsify the oils into the main candy mixture.

You don’t want to overheat and degrade any of the cannabinoids.

A mug warmer or candle warmer, as they are called, is amazingly handy for mixing cannabis oils at home.

They are inexpensive, and I can usually find them in thrift stores!

How to Make THC Gummy Bears

1. Combine unflavored gelatin and water in a saucepan, allowing it to dissolve or “bloom.”
   
2. Separately, mix lecithin, glycerin, and FECO, warming to emulsify. Set aside.
   
3. Incorporate flavored jello and corn syrup into the gelatin mixture on low heat until blended.
   
4. Once off the heat, add LorAnn Oil flavoring or food-grade essential oils, optional mold inhibitor, and your cannabis oil, ensuring thorough mixing.
   
5. Prepare silicone molds on a tray, cleaning if new. Lightly condition molds with a neutral cooking spray, wiping any excess.
   
6. Use a dropper or silicone bottle to fill molds and note the batch quantity for dosing calculations.
   
7. Chill molds in the fridge or freezer until candies are set.
   
8. Once set, pop candies out. Optionally, air dry for improved texture. (notes on air drying below)
   
9. Store in labeled airtight containers or bags. This recipe does not establish a validated shelf life, with or without mold inhibitor. Clearly mark as containing cannabis and keep locked away from children and pets.
   
10. Calculate dosage per candy piece for safe consumption. Always consume responsibly, start with a low dose, and be patient as edibles can take time to take effect. Remember, homemade gummies may have varied dosages.

Remember: Always keep away from children and inform adults they are medicated.

Pro Tips

1. Try making this recipe without cannabis first. Once you are confident, you can begin with the real THC gummy bears.
   
   
2. Look into CBD concentrates and other lesser cannabinoids to infuse your gummies with. You can make your own ratio with THC or skip the THC. This works as a great CBD RSO recipe as well.
   
   
3. The author uses refrigerated or frozen storage. A specific storage duration has not been verified for this recipe; do not assume mold inhibitor makes the batch shelf-stable.

Frequently Asked Questions

How to Air Dry THC gummies 

Drying is said to improve texture and make them more like store-bought candy.

Air drying changes surface texture; it does not establish a validated shelf life. 

To air dry, individually place each piece on a drying rack or a parchment-lined cookie sheet.

Cover the gummies with a flour-sack towel or other breathable lint-free cloth and allow them to dry for 24 to 72 hours.

Turn pieces as needed.

What are RSO Gummies?

RSO gummies are edible cannabis treats infused with Rick Simpson Oil, a potent cannabis extract. They offer a convenient and discreet way to consume cannabis, often with long-lasting effects.

What is in RSO Gummies?

RSO gummies typically contain a mixture of Rick Simpson Oil, gelatin or pectin, sweeteners, and flavorings. The RSO provides the active THC and/or CBD content.

What Does RSO Mean?

RSO stands for Rick Simpson Oil, a cannabis oil extract named after its creator, Rick Simpson. It is a highly concentrated form of cannabis oil that is often used for its potential therapeutic benefits.

Can this recipe tell me the exact strength of each gummy?

No. Extract weight, labeled THC content and the number of finished pieces are different measurements. Homemade pieces may also vary in size and distribution of cannabinoids. Treat estimates as estimates, not laboratory-verified doses.

What if my gummies are sticky or do not set?

Readers have reported both issues. Note the exact ingredient brands and forms, any substitutions, your mold size and the setting time when asking a recipe question. The author’s texture notes are included above; we have not independently tested a universal fix or replacement ingredient ratio.

Does mold inhibitor make these shelf-stable?

This recipe does not establish a validated room-temperature shelf life. Follow ingredient manufacturers’ directions and do not treat preservative use or a dry surface as proof that a homemade batch is safe to store at room temperature.

Where can I read about edible cannabis safety?

The CDC explains the delayed effects of edible cannabis and poisoning prevention. Keep products clearly labeled, in a locked child-resistant container and away from children and pets. For individual medical or dosing questions, speak with a qualified clinician.
