Common Conversion Mistakes & Fixes
🍪 Cookies spreading too thin?
Likely cause: Too little flour. You might have converted European grams incorrectly.
Fix: 250g flour = 2 cups (not 1.5 cups). European recipes often use 250g as standard.
🍰 Cake too dense?
Likely cause: Over-measured flour. Scooping compacts flour by 20-30%.
Fix: Use spoon-and-level method or switch to weight (125g per cup flour).
🧁 Frosting too runny?
Likely cause: Confused powdered sugar with granulated. They have very different densities.
Fix: 100g powdered sugar = 0.83 cups (NOT 0.5 cups like granulated).
The 20% Rule
When converting unfamiliar ingredients, remember: most dry ingredients fall within 20% of flour's density (125g/cup).
- • Lighter than flour: cocoa, cake flour, cornstarch
- • Similar to flour: whole wheat, bread flour
- • Heavier than flour: sugar, salt, rice
The European Standard
European recipes often use these standard amounts:
- • 200g sugar = exactly 1 metric cup
- • 250g flour = exactly 2 metric cups
- • 250ml liquid = exactly 1 metric cup
- • 500g = standard package size
