If using fresh fruit, give them a rinse and pat dry with a clean cloth. Remove any stems or green bits. For a more intense raspberry flavor extract, some people freeze and thaw the berries first to break down cell walls and release more color and flavor.
If you're starting with dried raspberries, there’s no prep needed; just make sure they’re food-grade and free from added sugar.
Add the raspberries into your clean pint-sized mason jar, along with the lemon juice, and optional vanilla or orange extract. Cover the berries with high-proof alcohol until they are fully submerged.
Add a lid to the jar and shake it gently. Label and date the jar and store it in a dark place at room temperature for at least 4 weeks, giving it a gentle shake every few days.
After about a month (I like to leave mine up to 8 weeks for a stronger flavour), strain the extract through a coffee filter, cheesecloth, or jelly bag into a clean glass bottle. Press gently on the solids with the back of a spoon to release as much extract as possible. It should have a beautiful red color.
Store in a dark place or cupboard.
