Spanish-style green olives
Spanish-style green olives, or Sevillian green olives, are green fruit treated with lye, rinsed, then fermented in brine for two to six months. The household batch here is a UC ANR method.
Traditional method
Berenjenas de Almagro · Dealmagro aubergine · Solanum melongena var. Dealmagro
A protected aubergine preserve from Ciudad Real in Spain: tender fruit of the local Dealmagro variety, cooked briefly and then fermented in a vinegared, paprika-seasoned dressing.

Berenjena de Almagro is a protected preserve of aubergine fruit from the Dealmagro variety, grown and processed in a defined group of seven municipalities in Ciudad Real, Spain. The fruit is cooked briefly, then fermented in a dressing of vinegar, oil and spices. The result is a soft, seasoned aubergine with a sharp, paprika-and-garlic flavour.
The 1995 regulation set the protected designation, and the 2012 specification now defines the rules. The specification's historical section is useful but attributed. It quotes a 1513 passage about aubergines in general, reports a local tradition of Arab origin without naming its scholars, and describes early twentieth-century household preparation in glazed earthenware pots by people skilled in seasoning.
None of these statements dates this exact named preserve. The sources support the modern protected product and its local preparation, not a medieval origin.
Picking runs from July into about November, every three or four days. The fruit is cooked for 5 to 20 minutes and then put into large fermentation vessels with the aliño, a dressing of vinegar, vegetable oil, salt, cumin, garlic, paprika and water. The mixture ferments for 4 to 15 days before it is packed in authorised containers such as cans or glass jars.
This is a hybrid process. Vinegar is an ingredient of the dressing, and fermentation is a separate, named stage. The sources do not say how much of the acidity comes from the added vinegar and how much from fermentation, and they name no starter culture.
The specification lists aliñadas (dressed whole fruit), stuffed fruit, fruit stuffed with a pepper paste, cogollos and chopped presentations. The 1995 regulation describes a stuffed form with a piece of pepper and a fennel stalk. These are forms of the product, not separate fermentation methods. The specification describes it as a first course or traditional aperitif.
The sources do not give a household batch, a container, a fermentation temperature, an endpoint test or a storage period. The specification's product pH below 4.5 is a controlled production characteristic and not a home safety test. A home method would need a validated process, which the sources do not provide, and qualified review before it is written as a recipe.
The 2012 specification quotes a 1513 passage about aubergines in general, attributes a local Arab-origin tradition to unnamed local scholars, and recounts household preparation in glazed earthenware pots in the early twentieth century. These are attributed heritage statements. They do not establish a medieval origin for this named preserve.
Scaling: source batch only
Cooked aubergine in a vinegared dressing is a product whose safety depends on controls the sources do not give for a home batch.
Hazard sourceUse a validated process and authorised packing before storing a batch.
Control sourceThe specification lists a product pH below 4.5 as a final characteristic. That is a controlled product description and is not a home endpoint. Appearance, smell and taste cannot establish that the product is safe.
Seven municipalities defined by the specification; production, processing and packing must take place in the area.
