Apple Marmalade Secrets: How Natural Pectin Gives That Perfect Gel

The secret to a thick apple jam that can be sliced like marmalade lies in natural pectin. Unlike commercial preserves, this version requires no starch or artificial thickeners. By managing the temperature and allowing the fruit to simmer slowly, you achieve a clear, amber-colored preserve that holds its shape perfectly—making it an ideal filling for pastries that won't leak during baking. Ingredients 2 kg tart-sweet apples 1 kg sugar Juice from 1/2 lemon Preparation Step 1. Peel the apples and remove all cores. According to chef Lyudmila Kravtsova, removing the skin is essential for a smooth, uniform consistency; otherwise, the final texture may be too coarse. Step 2. Cut the apples into slices and place them in a heavy-bottomed pot. Pour over the sugar and let the mixture sit for approximately two hours. This allows the fruit to release its own juice, eliminating the need to add water, which is critical for achieving maximum thickness.
