Next, I spread a thin layer of Dijon mustard onto half of these squares, giving that extra zing to every bite. Then, I layer on those lovely slices of ham, followed by two slices of cheese on top. I usually go for a mix of Swiss and cheddar because I adore the flavor combination. After stacking, I fold the other half of the pastry square over the filling and gently press down the edges to seal them. I like to use a fork to crimp the edges, adding both decoration and a secure closure.
Once all my stacks are assembled, I place them on a parchment-lined baking sheet. Before they go into the oven, I whisk the egg with a splash of water and brush the mixture over each pastry. This gives them that mouthwatering golden color as they bake. I pop them in the oven for about 20-25 minutes, or until they are puffed up and beautifully browned. The aroma that fills my kitchen is absolutely heavenly!
Pro Tips for Best Results
When I first made these stacks, I experimented with different cheeses. I found that a combination of cheeses worked best for flavor and melt factor, so don’t be afraid to mix things up! I once tried adding a sprinkle of spicy pepper jack in the mix, and let me tell you, it added a delightful kick that I absolutely adored.
Also, remember that puff pastry needs to be cold to function at its best. If you can keep it chilled while you work, you’ll get the flakiness that makes these stacks so divine! If at any point the pastry gets too warm and becomes difficult to handle, simply pop it back in the fridge for a few minutes to firm up.
Lastly, don’t skip the egg wash! It’s one of those small but mighty steps that creates that golden shine on the outside. I’ve tried these without the egg wash, and while they were still delicious, the visual appeal was definitely lacking. A little effort goes a long way in presenting your dish!
Common Mistakes to Avoid
One common mistake I made the first time was overstuffing the pastries. While it can be tempting to pile on more ham and cheese, I learned that a thin layer is really all you need. Overstuffing can lead to messy, bloated pastries with filling spilling out during baking, which, trust me, isn’t the look you want! (See the next page below to continue…)
