Quick answers

1/4 cup of jam or preserves is about 85 g, 1/3 cup is about 113 g, 1/2 cup is about 170 g, 2/3 cup is about 227 g, 3/4 cup is about 255 g and 1 cup is about 340 g (12.0 oz). One tablespoon is about 21.2 g and one teaspoon about 7.1 g.

Example: using jam or preserves in a recipe

If a recipe asks for 1 1/2 cups of jam or preserves, that is 1.5 x 340 g, or about 510 g. If a recipe gives 200 g and you only have cups, divide 200 by 340 to get about 5/8 cups.

How to measure jam or preserves

Thick spreads trap air pockets when you spoon them in. Press the jam or preserves into the cup, level it and scrape it out with a spatula. Weighing into a bowl is much easier than scraping a cup.

Where these weights come from

Weights follow the King Arthur Baking ingredient weight chart (rounded). Brands and measuring methods vary, so treat results as close estimates.
