Homemade Gummies From Scratch: Gelatin, Pectin and RSO Basics

Last Updated: October 2026 · Mercy Leaf

Homemade gummies are mostly about learning a few basics: bloom the gelatin, warm the juice and let everything set. We'll start with a plain batch, then talk about what the tested 75% THC content of Mercy Leaf RSO means.

Key Takeaways:
  • Gelatin and pectin need different recipes
  • Bloom gelatin in cool juice to avoid lumps
  • A small plain batch helps you learn texture
  • A smooth-looking infused batch does not prove even THC content

Recipe at a glance

This gelatin recipe shows how to bloom gelatin, warm juice and mold homemade gummies. If using RSO, the recipe also explains how to prepare an edible-oil premix and blend it into the warm gummy base before molding. The recipe does not promise uniform THC content in untested finished pieces.

Preparing Your RSOPreparing RSO for Gummy Mixtures · View preparation steps
  1. Prepare the gummy base first and ready the molds so the batch can be filled promptly.
  2. Soften the sealed RSO syringe gently in a waterproof bag in warm water and measure the intended extract.
  3. Premix the RSO with a little compatible edible oil for an oil-based formulation, or with a small portion of warm melted candy for a remelted-candy recipe.
  4. Stir the premix into the still-fluid gummy mixture and mold promptly. Check for signs of separation.

Oil-like RSO and water-based gummies can separate. An emulsifier may help disperse oil but cannot establish equal THC per gummy.

For this recipe: For gelatin gummies, choose a compatible oil premix and add while the base is still fluid.

Instructions

  1. Bloom

    Pour some cool juice into a bowl, sprinkle the gelatin evenly on top and let it absorb the liquid as directed on the package. This helps avoid lumps.

  2. Warm

    Warm the remaining juice gently. Add hydrated gelatin and stir until fully dissolved; avoid boiling. If using RSO, follow the standardized Preparing Your RSO block above before molding.

  3. Mold

    Set the molds on a tray, pour carefully and refrigerate until fully set. Give them time to firm up before unmolding.

Tips and troubleshooting

Lumpy? Bloom the gelatin in cool juice first. Too soft? Double-check the gelatin ratio and setting time. Foamy? Stir more gently and skim the surface before filling molds.

Storage and labeling

Refrigerate promptly in a covered container. Homemade gelatin gummies have a shorter, variable shelf life than commercial shelf-stable candy.

Important safety notes

The plain version contains no RSO. The optional RSO-and-carrier premix changes the recipe, and a visually smooth batch is not proof of equal THC content in each gummy. Mercy Leaf’s 75% source-RSO reference is about 750 mg THC per gram before processing. Keep infused sweets labeled and locked away from children and pets.

Educational information only. Keep intoxicating preparations clearly labeled, securely stored and away from children and pets. Avoid driving while impaired.

From-scratch gummy math example: At 75% THC, 0.1 g of Mercy Leaf RSO contains about 75 mg THC before processing. If a batch yields 30 pieces, 75 ÷ 30 = a theoretical average of 2.5 mg per piece. The calculation does not demonstrate that each piece actually contains 2.5 mg; oil-water separation and incomplete mixing may cause substantial variation.

Start by choosing your gummy style

Gelatin gummies are a friendly first project because they set as they cool. Pectin gummies are a different kind of candy-making: depending on the pectin, sugar, acid or calcium may be necessary for a reliable set. Don’t swap pectin for gelatin tablespoon-for-tablespoon and expect the same result. For your first batch, learn one system before experimenting.

Make a plain gelatin batch first

For a small non-infused batch, set out one cup of fruit juice, two tablespoons of unflavored gelatin and optional sweetener. Set silicone molds on a tray. Sprinkle the gelatin over a portion of cool juice and leave it to hydrate according to the package directions. Warm the remaining juice gently, stir in the hydrated gelatin until dissolved and pour into the molds. Refrigerate until set.

The trick is patience. If you dump dry gelatin straight into hot liquid, it often clumps. If you boil the mixture hard, the result may be disappointing. Let the molds rest until the gummies are firm before turning them out.

How to troubleshoot your first batch

Too soft? Check that the gelatin had time to hydrate and that your proportions matched the package. Lumps? Hydrate gelatin in cool liquid next time. Foamy tops? Stir gently and skim foam before filling molds. Sticky pieces? Added moisture and your choice of juice can make a difference. Keep a note of the juice, gelatin brand and setting time.

What changes when you consider RSO

RSO behaves differently from fruit juice because cannabinoids are largely oil-soluble. A gummy can look uniform while containing unevenly distributed extract. Ingredients sometimes called emulsifiers, such as lecithin, may help oil disperse but do not prove equal THC content from piece to piece. Start by understanding the plain recipe and the source extract before making assumptions about an infused version.

Finish with storage, not guesswork

Homemade fruit gummies are not automatically shelf-stable. Keep practice batches refrigerated, use clean utensils and discard anything with mold or an unusual smell. Infused candy needs clear labeling and locked storage, especially because it looks exactly like a regular snack. For additional context, see our gummy consistency guide.

Questions about this guide

No, they’re different ingredients. Choose a recipe designed for the gelatin or pectin you’re actually using.

Lecithin may help oil disperse, but it doesn’t prove that each gummy contains the same THC.

Don’t assume they’re shelf-stable. Refrigerate homemade fruit gummies and discard them if they spoil.

Usually it’s moisture moving through the candy or collecting on the surface. Look at the recipe and storage conditions.

Testing is needed if you want to make accurate claims about THC per piece or shelf life.

Mercy Leaf RSO is tested at 75% THC by weight. That works out to about 750 mg THC in one gram of source RSO. It’s a useful starting number, but finished gummies, brownies, oils and balms may not have evenly distributed THC.

Final thoughts

Your first batch doesn't need to be perfect. Pay attention to what works and make one change at a time next time.
