Nutrition Facts

To avoid lumps, "bloom" gelatin first by sprinkling it over cold liquid and letting it sit for 5 minutes before gently heating to dissolve. Do not boil dissolved gelatin, as it can reduce its gelling power.
Substitutions
Agar-Agar
Plant-based, creates a firmer, less wobbly gel. Requires boiling to activate.
Cornstarch
Thickens but does not create a firm, bouncy gel. Best for sauces and gravies, not molded desserts.
Pectin
Fruit-derived, used for jams and jellies. Requires sugar and acid to set.
Xanthan Gum
1:4A powerful thickener and stabilizer, but creates a gummy rather than a firm jelly texture.
Buying Guide
Available in powdered or sheet form. Powdered is easier to measure, sheets yield clearer gels.
