Old-Fashioned Egg Sandwich with Citrus Zest

Method

1. Heat the oven and prepare your pan; measure unsalted butter and avocado precisely.

2. Combine the dry and wet ingredients just until smooth, without overmixing.

3. Fold in eggs and transfer the batter to the pan, leveling the top.

4. Bake until set and golden and a tester comes out clean.

5. Cool before slicing so the egg sandwich holds its shape.
