Where it comes from
Tarta de Santiago is the cake of pilgrims arriving at Santiago de Compostela. First documented in 1577 in convent records of Santiago, refined through 19th-century pastelerías in the cathedral's old town. The Cross of Saint James stencil — the sword-cross used as the symbol of the Order of Santiago — became the official mark in 1924 and now defines the IGP (Protected Geographical Indication). Authentic versions must use minimum 33% Spanish-grown almonds.
On the plate
Cuts cleanly into wedges with a damp, dense crumb the colour of wet sand, perfumed with lemon-and-cinnamon, sweet but not cloying. Each forkful is mostly almond — texture closer to marzipan than sponge — and the powdered-sugar cross on top dissolves on the tongue first. If yours is dry it baked too long; if it's gummy at the centre, the egg foam wasn't aerated enough.
How it works
No flour means no gluten, so structure is entirely from the egg foam — that's why whipping the eggs to the ribbon stage matters more here than in any flour-based cake. The almond's fat sits inside the foam like a coffee-cake crumb, and the cake stays moist for days because almond oil doesn't stale the way wheat starch does. Lemon zest is structural too: its citric acid sets the egg proteins faster, giving a tighter crumb.

Variations
Casa Mora in Santiago's old town runs the IGP-certified version; Pastelería Compostelana goes denser; home cooks in Lugo often add a splash of orujo to the batter.

Heat oven to 175°C. Butter and flour a 24cm round cake tin. In a large bowl whisk 5 large eggs with 250g caster sugar 4 minutes until pale and ribbon-thick.
Watch outUnderwhipped eggs give a flat dense cake — keep whisking until the trail holds 3 seconds.
- 24 min
Fold in 250g finely ground blanched almonds (almond flour, not meal — coarse meal makes the cake gritty), the zest of 1 lemon, 1 tsp ground cinnamon and 1 tbsp sweet almond liqueur or brandy. Stir until just homogeneous.
Watch outDon't overwork — almond flour has no gluten but air will collapse.
- 335 min
Pour into the tin, smooth the top, and bake 30-35 minutes until the top is golden and a skewer comes out with a few moist crumbs. The centre should still tremble very slightly when nudged.
Watch outOvens vary — start checking at 28 minutes, the cake dries out fast past doneness.

Cool fully in the tin, 1 hour. Almond cakes firm and improve as they cool — slicing warm gives a crumbly mess.

Lay a paper stencil of the Cross of Saint James (Cruz de Santiago, the sword-shaped cross) on the cake top. Sift powdered sugar generously over it. Lift the stencil straight up — the cross stays printed in white.
Watch outLift the stencil vertical, no sliding — any drag smudges the cross edge.
