Crumb Cake with Jam – Pareve version

👨‍🍳 Method

To assemble

1. 1
   Preheat the oven to 180°C (355°F) and grease Pan of 24 cm and line it with parchment paper.

   ⚙ Preheating the OvenOven

   💡Put things in the oven only once it's reached temperature, after the heating light has gone off: an oven that hasn't reached temperature changes baking times, and the bake burns outside or stays underbaked.
2. 2
   Whip the soft margarine with the sugar, until pale and fluffy.

   💡Cream the margarine soft, at room temperature: cold margarine doesn't take in air, and melted margarine doesn't hold it.
3. 3
   Add the eggs one at a time, beating after each until absorbed.

   💡One egg at a time, and only when the previous one is absorbed: that way the emulsion holds and the batter doesn't split into curds.
4. 4
   Add the vanilla and mix.
5. 5
   Add the flour, baking powder and salt and Fold gently, just until no dry flour remains.

   💡Fold with a spatula, in broad strokes from the bottom up, and stop when there's no dry flour: vigorous mixing of a batter with flour develops gluten.
