Jam / Fruit Preserves — Frequently Asked Questions

320 grams of jam is exactly 1 US cup. Jam is one of the densest common baking ingredients due to its high sugar and fruit solids content.
Slightly. Smooth jams like strawberry or apricot are 310-330g per cup. Chunky marmalades or preserves with large fruit pieces can be 290-320g due to air pockets around the fruit.
For sticky ingredients like jam, spray the measuring cup lightly with cooking spray first, then fill and level. Or weigh in grams — far easier and more accurate than trying to scrape a sticky cup clean.
Very close. Preserves contain larger fruit chunks than smooth jam, so they may be 5-15g lighter per cup. Jelly (no fruit solids) is slightly lighter still. For most recipes, you can treat them as equivalent.
1 tablespoon of jam is approximately 20g. There are 16 tablespoons in 1 cup (320g total).
