Equipment
To make homemade jello, you’ll need:
- Small Saucepan
- Whisk
- Mold
- Plastic wrap (optional)
Instructions
Step 1: Bloom gelatin
First, we need to bloom gelatin, here is how to do that:
- Powdered Gelatin: Place gelatin granules in a bowl and pour in 150 ml (0.6 cup) of cold water. Let it sit for 5-10 minutes until the gelatin is set.
- Gelatin Sheets: Submerge the sheets in a tall glass of cold water (the amount of water doesn’t matter). Wait until they soften, then gently squeeze out any excess water.

Step 2: Dissolve sweetener, add gelatin
Meanwhile, pour the berry juice into a saucepan and add erythritol. Turn on low heat and stir until the sweetener dissolves completely. Avoid boiling the mixture.
Once the sweetener dissolves, add the bloomed gelatin and stir frequently until it’s completely dissolved. Ensure the berry mixture with gelatin doesn’t boil.

Step 3: Chill jello
Grease the mold with coconut oil, then pour in the jello mixture.
Allow to cool down to room temperature. Then, refrigerate for several hours or until the jello is set. Setting time may vary, but it should be stable within a few hours.

Tips for the best results
- Dissolve gelatin in cold or ice water.
- Avoid letting the gelatin mixture boil, high heat breaks down the gelatin’s gelling power.
- Place the form/container in the freezer before adding the berry mixture. This will speed up the gelatin stabilization process.
- Cover the form with plastic wrap to prevent the surface from drying out. This helps to maintain the dessert’s moisture and freshness.

What is better for keto diet: jello or gelatin?
For a low-carb diet, gelatin is a much better option than Jello. Here’s why:
- Sugar Content: regular jello mixes typically contain a significant amount of added sugar or artificial sweeteners, significantly spiking your sugar intake and potentially kicking you out of ketosis. Plain gelatin, on the other hand, is sugar-free, making it a clear winner for keeping your blood sugar levels in check, a crucial aspect of the ketogenic diet.
- Additives: Jello mixes often contain artificial colors, flavors, and thickeners. While some brands might offer sugar-free versions, these often include artificial sweeteners that can still affect your ketosis or might not be ideal for everyone on a low carb diet. Plain gelatin has no additives, allowing you more control over your ingredients.
- Protein Content: Gelatin is a source of protein, which can help with satiety and contribute to a healthy diet. This can be beneficial on a keto diet, where feeling full is important for managing cravings.
How Gelatin is beneficial for the health?
- Gelatin can be beneficial for joint, muscle, bone, skin, gut, hair and nail health.
- Gelatin is rich in protein and full of unique amino acids.
- Promotes the production of collagen.
- One tablespoon of gelatin contains 5-6 calories, 0 g carb, 1-2 g protein, 0 g fat.
