This is one of those very useful things - a brunch recipe that you can prepare in advance, make for large numbers and is very simple, but tastes brilliant and is a real crowd-pleaser. They contain about a million calories, so I would recommend only having this for special occasions. And have some orange juice in your champagne, to make you feel more virtuous.
Because it is so simple, it pays to use some nice ingredients.
Ham & Cheese Croissants (serves 2)
4 croissants (all butter ones, not the ones with weird fats and shortening in them, and not the absolutely huge ones)
4 thick slices of good ham (this was a dry-cured, cherrywood smoked ham)
4 thick slices of gruyere cheese
Preheat the oven to 160C. Cut each croissant in half. Smear the cut surfaces with a little mustard. Fill each with a slice of ham and a slice of cheese. Put the top of each croissant back on and place them on a baking parchment-lined baking sheet. Bake for about 10 minutes, or until the croissants are browned and the cheese is oozy and beginning to take a bit of colour. Allow to rest for a couple of minutes before serving, just to avoid all your guests burning their mouths.
