For this recipe, I ended up making the yolks three ways—one batch of plain salt cured egg yolks, one with some peppercorns mixed in, and one with some red chili flakes mixed in. You can make a big batch like the recipe calls for, or you can cut it in half or down by 2/3 to make smaller amounts. It's totally your call! I ended up keeping about 3 of the finished ones in the frig, then I wrapped each of the remaining cured egg yolks in plastic wrap, then put them in a Tupperware container and froze them, so that way I can just take them out one at a time going forward and have enough to last me the rest of the year. They will keep in the refrigerator in an airtight container for up to 2 weeks.
