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.
