I grow my own jalapenos, so they are always available.
If I am cutting the jalapenos in half, I use a metal baby spoon, and run the pepper under cool water to remove the seeds. Really fast, and the little spoon just pops those seeds right how.
I precook my bacon until it's almost done.
If I'm making about 10 jalapenos (20 half's) I use one small cake of Phili cream cheese, and equal amount of extra sharp cheddar cheese. Mix until all is integrated.
Stuff the jalapenos, and either wrap, or place bacon on top (It's easier to just put the bacon on top) and bake at 350 for about 1/2.
If your doing whole jalapenos, you may want to blanch them for about 2-3 mins in boiling water.
I prepare one day a head, sliced water chestnuts in brown sugar, and soy sauce to marinate in the frig.
I stuff some cheese mix in the bottom, place the water chestnut in the middle, then fill the rest of the pepper up with the cheese mix, and place the top back on.
I bake them at 350 for about 20-25 mins if blanched, 45 mins if not.
