Step 5: Stir and Wait
Between heating increments, stir the mixture to promote even heat distribution. This step is crucial because microwaves can heat unevenly, leading to hot spots that may cook parts of the yolks instead of pasteurizing them uniformly.
Step 6: Cool Down
After reaching the desired temperature, remove the bowl from the microwave. Allow it to cool slightly before using the pasteurized egg yolks in your recipes.
Step 7: Store or Use Immediately
If you are not using the pasteurized yolks immediately, store them in an airtight container in the refrigerator. Pasteurized egg yolks can be refrigerated for up to 24 hours.
Safety Tips for Pasteurizing Egg Yolks
While microwave pasteurization is straightforward, following these safety tips can ensure optimal results:
Use Fresh Eggs
Choose fresh, high-quality eggs, as they have a lower risk of contamination.
