How to Measure Jam Accurately

To measure jam accurately, coat the measuring cup with a thin film of oil first, so all of the jam slides out.

  1. 1

    Coat the cup with oil

    Wipe a thin film of neutral oil or cooking spray inside the measuring cup.

  2. 2

    Fill the cup

    Pour or spoon the jam in until it reaches the rim or the measurement line.

  3. 3

    Scrape it out

    Use a flexible spatula to scrape the cup clean. Leftover residue shortens the recipe.

  4. 4

    Weigh it for an exact amount

    Set a bowl on a kitchen scale, press tare, and add jam until the scale shows the gram amount in the recipe.
