We’ve identified the chillies my dad grows as being of the Padrón variety, which, according to this article are being marketed in the UK now as “Russian Roulette Chillies”, as the degree of hotness is so variable from one chilli to the next.

“In Spain they are very trendy right now where they are used for a bit of fun in a daredevil game of culinary Russian roulette.

“But they all have a superb, sweet, fresh taste not too dissimilar to bell peppers or even freshly picked asparagus.”

They are traditionally cooked in a pan with a small amount of olive oil until they blister, with guests then encouraged to take their chances.

According to wikipedia’s page on tapas, Padrón is a municipality in the province of A Coruña in the region of Galicia.
