Prepare a brine with sugar and spices to turn cucumbers into delicious pickles, focusing on the science of flavor infusion.

In a medium saucepan, combine water, white vinegar, granulated sugar, and salt. Heat over medium heat until sugar and salt dissolve completely.
Per serving
Add black peppercorns, red chili flakes, and mustard seeds to the brine. Stir to mix well.
Remove the brine from heat and let it cool to room temperature. This is important to prevent cooking the cucumbers when added.
Once cooled, place sliced cucumbers in a clean glass jar. Pour the brine over the cucumbers, ensuring they are fully submerged.
Seal the jar tightly and refrigerate for at least 24 hours before enjoying the pickles. The longer they sit, the more flavor they will develop.
