Preheat oven to 350F/180C.
Add sourdough discard, flour, soft butter, salt, shredded cheese, honey and diced jalapeños to a mixing bowl and bring the ingredients together to form a pliable dough (see notes).
Divide the dough into two portions (this makes it easier to roll).
Place each ball onto a piece of parchment paper and flatten out with your hands into a rough rectangle.
Now roll out to a thin sheet of dough using a rolling pin. You want it around 1/16" or 1.5mm thick.The dough should not be sticky at all and easy to roll - however see notes below for some troubleshooting if your dough is sticky. Use a cracker roller to perforate dough. If you don't have a cracker roller you can use a cookie cutter or knife to cut into crackers and then pierce each one with the tines of a fork.
Place each parchment paper with dough on top onto a baking sheet. This recipe will generally need two baking trays.
Brush dough with olive oil and sprinkle with salt.
Bake at 350F/180C for around 25 minutes or until crackers are golden and crisp.
Let the crackers cool on a rack before breaking into individual pieces.
