Potro!

In the supermarket earlier today, I was looking for a nice piece of beefsteak when my eye was caught by a very delicious looking piece of meat, shown in the photo below, called "Solomillo de Potro".

Solomillo is a very good cut of meat, called "sirloin" in the UK, but potro is "colt"!
Supermarkets in the UK have had problems with horsemeat being found in their "beef" dishes. Here it isn't disguised as anything - you can buy it for what it is.
I gave it a miss this time however - it was too expensive!
