A question about a recipe: Crostini with Whipped Goat Cheese and Hot Pepper Jelly

I have a question about step 1 on the recipe "Crostini with Whipped Goat Cheese and Hot Pepper Jelly" from apartmentcooker. It says:

"Halve the jalapenos. Seed the jalapenos based on how spicy you want the jelly. (Since red jalapenos are sweeter than green jalapenos, I seeded half of the jalapenos, but left the seeds with the other half. It made for a only slightly spicy jelly. Final spice can also be adjusted with red pepper flakes at the end of cooking.)
