- Why does the cake collapse?
- If you mix the egg white foam too quickly or roughly into the heavy poppy mixture, the air bubbles burst, and the batter loses volume.
- The poppy seeds are bitter, what should I do?
- The oil content in poppy seeds goes rancid quickly. Always use freshly ground poppy seeds or taste before using.
Classic Poppy Seed Cake
The use of poppy seeds is a cultural speciality in Central European confectionery. While rare in the West, for us, it is a symbol of abundance. Chemically, the high oil content of poppy seeds ensures the cake's moistness, requiring less added fat. The structure of the foam-leavened batter relies on protein solidification and retaining air bubbles, which must be maintained despite the heavy poppy seeds.

Instructions
1
✓
Cream the butter with half of the icing sugar until pale, then add the egg yolks one by one.
Tip: Creaming incorporates air into the fat. Sugar crystals cut tiny air bubbles into the butter, which expand from heat during baking, lifting the cake.
2
✓
Mix the ground poppy seeds, lemon zest, and breadcrumbs into the butter mixture.
Tip: The essential oils in the lemon zest balance the heavy, oily taste of the poppy seeds.
3
✓
Whisk the egg whites with the salt and remaining sugar until stiff peaks form but are not dry.
Tip: Salt stabilises the foam, but add sugar only at the end for a glossy and stable structure. If overbeaten (lumpy), the proteins release water (syneresis).
4
✓
Stir one-third of the egg whites boldly into the poppy mixture (to loosen it), then gently fold in the rest.
Tip: The 'folding' technique (lifting from bottom to top) aims to preserve mechanical air. Poppy seeds are heavy, so work quickly but delicately.
5
✓
Bake at 180°C for approx. 40 minutes. Skewer test obligatory.
Tip: Do not open the oven door in the first 20 minutes, as the thermal shock will cause the cake's structural framework to collapse before setting.
