Why Egg Size Matters

Too Large Eggs:

  • • Too much liquid → soggy texture
  • • Cakes may sink in middle
  • • Cookies spread too much

Too Small Eggs:

  • • Dry, crumbly texture
  • • Poor rise in cakes
  • • Insufficient binding

Quick Tips

  • Room temperature: US recipes often specify this; UK eggs need 30 min out of fridge
  • Free-range variations: Can vary ±10% in size, always weigh for accuracy
  • Freshness test: Fresh eggs sink in water, old eggs float
  • Emergency measure: 1 large egg ≈ 3 tablespoons beaten egg

Perfect Meringue Ratio

2 : 1

Sugar : Egg Whites (by weight)

200g sugar + 100g egg whites

100g egg whites ≈ 3 large eggs

Three Types of Meringue

French Meringue

Method: Beat raw egg whites + sugar

  • ✓ Easiest, lightest
  • ✓ Best for: Pavlova, baked meringues
  • ⚠ Must bake fully
  • ⚠ Not stable for piping long

Ratio: 2:1 sugar to whites

Bake 200°F 1-2 hours

Swiss Meringue

Method: Heat whites + sugar, then beat

  • ✓ Silky, stable
  • ✓ Best for: Buttercream, pie topping
  • ✓ Safe to eat (pasteurized)
  • ⚠ Requires double boiler

Ratio: 2:1 sugar to whites

Heat to 160°F, then beat

Italian Meringue

Method: Pour hot sugar syrup into whites

  • ✓ Most stable, glossy
  • ✓ Best for: Macarons, frosting, mousse
  • ✓ Safe to eat (cooked)
  • ⚠ Requires candy thermometer

Ratio: 2:1 sugar to whites

Sugar syrup to 240°F (soft ball)

French Meringue Recipe (Easiest)

Ingredients

  • Egg whites (room temp) 100g (3 large eggs)
  • Granulated sugar 200g (1 cup)
  • Cream of tartar ¼ tsp
  • Vanilla extract ½ tsp

Instructions

  1. 1. Beat egg whites + cream of tartar to soft peaks.
  2. 2. Add sugar 1 tbsp at a time, beating 30 sec between.
  3. 3. Beat to stiff, glossy peaks (8-10 min total).
  4. 4. Test: peaks stand straight, bowl can invert.
  5. 5. Pipe or dollop onto parchment. Bake 200°F 90 min.
  6. 6. Turn off oven, leave inside 1 hour (crisp shell).

🥚 Egg White Tips

Room temp whites beat faster • No yolk at all (fat = failure) • Metal or glass bowl (plastic holds oil) • Humid days = sticky meringue

Meringue Troubleshooting

Problem Cause Solution
Won't form peaks Fat contamination (yolk, oil) Start over with clean bowl + fresh whites
Weeping (beads of liquid) Undissolved sugar or humidity Use superfine sugar, bake lower/longer
Deflates when baking Underbeaten or oven too hot Beat to very stiff peaks, lower temp to 200°F
Gritty texture Sugar not dissolved Add sugar slower, beat longer, use superfine
Sticky or chewy Underbaked or humid weather Bake until dry, store airtight immediately
