About Corn Syrup

Pour into a level measuring vessel and allow thick syrup to settle before reading it. Transfer the syrup with a scraper, or weigh it directly into a tared bowl to avoid transfer losses.

Light and dark corn syrup can give different colour and flavour. A conversion only sets an amount; in a candy recipe, also respect the specified syrup and cooking temperature.

Tips for measuring Corn Syrup

  • Let bubbles settle before reading the cup.
  • Use the light or dark variety specified.

Common mistakes

  • Treating pancake syrup as the same product as corn syrup.
