Grab a handful of cucumbers, cut the top off where the stem attaches, and cut the larger ones into spears (or halves) as you see fit.
Put half of the slightly crushed garlic (2-4 cloves) into the bottom of the jar, pack about 1/2 way up the jar with pickles, add some additional garlic, pack in a few sprigs of dill, and one small chili pepper. Proceed to pack the rest of the jar with cucumbers, leaving space at the top.
Pour or ladle in your brie, being sure to add at least a few coriander seeds, and peppercorns, Then, screw on your lid hand tight, yet firm.
Place the sealed jars back in the boiling water, and boil for about 10 minutes. When you add your jars, the water will likely stop boiling for a short time. Ensure you start your timer as the water comes back up to a boil.
Remove jars using a specialized canning tool,, and place on a wood cutting board (or similar) to cool for no less than 12 hours. Once cool, store in a cool, dry place, out of direct sunlight.
Pickles should be good for up to 1 year on the shelf, and 2 months in the fridge once opened, however I'd typically suggest to try and eat them within a month.
