This popular Irish cafe food is a cinch to prep and whip up at home with just a few ingredients. Pastries can be made and frozen ahead of time, or eaten hot or at room temp. Makes a great appetizer, game-day snack, or even light meal. Ingredient measurements are approximate, and feel free to substitute your favorite cheese.
Preheat oven to 400℉ and line 2 baking sheets with parchment or silicone liners.
Let pastry sheets thaw in fridge. Lay out on lightly floured surface and use a rolling pin to roll them out just a bit larger than their given size. You'll need to cut dough into even squares (can be larger or smaller depending on your preference) so you may want to grab a ruler to make sure you've got it at a good size to cut even squares. I like to cut into 9 squares for small bites and just 6 for larger, more traditional size.
Place a good amount of cheese and a sprinkle of ham in the center of each square. Be generous. Then take the corners of each square and pull them up to the center and pinch to close. (They will open back up during cooking and that's okay!)
Whisk your egg with 2 tablespoons water in a small dish and then brush egg wash over the top of each sealed square.
Bake at 400℉ for about 20-25 minutes, until puffed and golden brown.
Notes
If you'd like to re-heat leftover pastries from room temperature or fridge, simply place on a baking sheet in a 375℉ oven for just a few minutes, until heated through again. They can also be reheated in the air fryer for 2-3 minutes at 350℉.
You can also prepare these and freeze PRE or POST baking. To cook, place frozen pastries directly on baking sheet and bake as directed. They'll need a few extra minutes.
Serving size depends on size cut; this recipe will make anywhere from 12 - 18 pastries.
Finished jambons can sit at room temperature for up to two hours. Store cooled jambons in an airtight container in the refrigerator and enjoy within 2-3 days for best results.
