A tart can be old and still have a short paper trail. This one has a very short one.
What it is
Spain’s agriculture ministry, in a product sheet dated November 2008, describes a traditional Galician sweet made mainly from almonds, sugar and egg. It is round, with a powdered-sugar topping that shows the Cross of the Order of Santiago. The sheet describes a yolk-and-almond aroma, a white surface, a golden cut and a spongy, granular texture. Wikipedia calls it the best-known cake of Galicia and says it can be made with or without a pastry base.
What the protected name requires
The ministry sheet sets out the percentages, as shares of the total dough weight.
- Almonds: more than 33%. They must be first quality, with more than 50% fat measured on the unpeeled product.
- Refined sugar: more than 33%.
- Egg: more than 25%.
- Pastry casing, if there is one: at most 25% of the weight of the whole tart.
The sheet adds that lemon zest, sweet wine, brandy or orujo spirit, and powdered sugar go in as the method calls for. The casing is either puff pastry (wheat flour, butter, water, salt) or shortcrust (wheat flour, butter, sugar, whole egg, milk, salt). The geographic area is the whole of Galicia.
The Galician regional food agency’s technical sheet for 2025 gives the same minimum of 33% almonds of the total dough weight and names the Cross of the Order of Santiago as the product’s distinguishing sign. It counts 10 producers as of 31 December 2025. A lifestyle magazine, Hola, gives the formula as 33% almond, 33% sugar and 25% egg, requires the round shape, and says the protection covers two versions, without a base and with a pastry base. Wikipedia says the cake must be made in Galicia and contain at least 33% almonds, excluding the base.
Notice the wording. The ministry says “more than”; the agency and Wikipedia say “at least”. We show both and do not choose. Our reading: the difference is small, but anyone quoting the rule should say which text they are quoting.
Dates in order
The protection has several dates in the sources.
- 2006: Hola says the process began this year. Wikipedia’s references cite a 2006 Spanish resolution.
- 10 February 2010: the regional agency says an order of this date approved the regulation and the regulatory council. It was amended on 10 June 2016.
- 10 May 2010: the agency says an EU Commission regulation of this date registered the name, published in the Official Journal on 11 May 2010.
- May 2010: Wikipedia gives this month for the protected status.
- 2010: Hola gives the year.
Wikipedia’s references also cite a 2007 registration number and a 2009 journal publication, and it does not explain the order. The ministry sheet cites a royal decree of 2007 and gives no registration date. We leave the early dates there.
Where the story starts
Three sources tell the history.
The ministry sheet says almonds reached Galicia by sea from eastern Spain in the late Middle Ages, were costly and were linked with wealthy tables. It says almond sponge cakes appear in Galician sources from the 16th century on and traces the tart to aristocratic and clerical kitchens of the 16th to 18th centuries.
The earliest reference is dated 1577. The ministry sheet describes it as a “torta real” of ground almonds, sugar and eggs, baked and served at a University of Santiago event, and says the source is imprecise and should be read with caution. Wikipedia places the record in notes on food eaten at the University of Santiago. Hola says a clergyman, Pedro de Portocarrero, called it “Torta Real” and served it in individual portions. The three accounts are close, but only Hola names a person.
The earliest reliable recipe, says the ministry sheet, is in a confectionery notebook compiled by Luis Bartolomé de Leybar around 1838. Hola dates the recipe book to 1838 and calls him a confectioner.
Wikipedia adds an older story: a food writer it cites links the cake to the 11th century and to Jewish communities bringing an almond Passover cake north. Wikipedia itself calls this a traced origin, not a documented one, and the earliest documented record remains 1577. We pass it on as a claim and no more.
The cross
The ministry sheet and Hola agree that the cross came later than the tart. José Mora Soto, founder of the Santiago confectioner Casa Mora, decorated his almond tarts with a silhouette of the Cross of Santiago in 1924, says the ministry. Wikipedia also gives 1924 and says the shop began using the stencil that year. Hola adds that the cross became common from then, and that Casa Mora closed in 2002.
The sources name the Order of Santiago and say no more about it, and we add nothing.
Without a base, or with
Hola says the original version, without a base, is made from ground almond and no cereal flour, so it contains no gluten, and that versions with wheat, corn or commercial mixes are not considered the authentic tart. That is the magazine’s view. The ministry sheet lists wheat flour only inside the pastry casing. We did not find a source that says the protected name bans flour in the filling beyond Hola’s statement.
What kind of sources these are
A government ministry’s product sheet, a regional agency’s technical sheet, an encyclopaedia and a lifestyle magazine. The first two are the closest to the rules.
What we left out
Prices, shop names beyond the historical one, recipes and any health advice.
