Lemon Loaf
A tight, buttery crumb soaked with lemon syrup and finished with a sharp glaze.
What's going on here
Almost all of a lemon's aroma lives in the oil glands of the peel, not in the juice — the juice is mostly citric acid and water and tastes sour rather than lemony. So the first step is rubbing the zest into the sugar with your fingers: the sugar crystals act as an abrasive, rupturing those glands and releasing the oils into a medium that carries them through the whole batter. Skipping this and just stirring zest in gives a noticeably flatter loaf. The syrup soak is the second half of the idea. Brushing lemon syrup onto the loaf while it's still hot works because the crumb's structure is open and its water is still evaporating, so it draws the syrup in by capillary action; the same syrup on a cold loaf just sits on the surface and makes it sticky. Butter rather than oil here, because this loaf wants a tighter, cakier crumb than the fruit breads.
Ingredients
Batter
- 1 cupGranulated sugar
- 2 tbspLemon zest
from about 3 lemons
- 1/2 cupButter, softened
- 3Eggs
- 1/2 cupMilk
- 2 tbspLemon juice
- 1 3/4 cupsAll-purpose flour
- 1 1/2 tspBaking powder
- 1/2 tspSalt
Syrup
- 1/4 cupLemon juice
- 1/4 cupGranulated sugar
Glaze
- 1 cupIcing (powdered) sugar
- 2 tbspLemon juice
Instructions
Batter
- Put the sugar and lemon zest in a bowl and rub them together with your fingertips until the sugar is damp, clumpy, and intensely fragrant.
Tip: This is the most important step in the recipe. The sugar crystals are tearing open the oil glands in the zest — you'll smell the difference immediately.
- Add the softened butter and cream with the lemon sugar until pale and fluffy, about 3 minutes.
- Beat in the eggs one at a time, then the milk and 2 tbsp lemon juice. The mixture may look slightly curdled — that's the acid, and it corrects once the flour goes in.
- Whisk the flour, baking powder, and salt together and fold in just until combined.
Bake
- Bake at 175°C (350°F) until golden and a skewer comes out clean.
Syrup
- While it bakes, warm the syrup lemon juice and sugar together just until the sugar dissolves. As soon as the loaf comes out, poke it all over with a skewer and brush the syrup over the hot loaf, letting it soak in between coats.
Tip: It must go on hot. A cooled loaf can't absorb it and you'll just get a sticky top.
Glaze
- Cool completely, then whisk the icing sugar and lemon juice into a thick glaze and pour it over the top.
Tip: Completely cool, or the glaze melts and runs straight off the sides.

Tips for this recipe
Zest before you juice
Zesting a lemon that's already been squeezed is miserable. Take the zest off the whole fruit first, then juice it.
Only zest the yellow
The white pith underneath is bitter and contributes nothing. Use a fine grater and stop as soon as you see white.
