Fresh ricotta is best the day it's made but can be stored in an airtight container in the refrigerator up to four days. Don't waste the protein-rich whey that drains out of the ricotta curds. Freeze it in ice-cube trays and use in smoothies, or simply enjoy it as is, poured over ice.
The idea behind this beautiful and delicious salad is to use up all the remnants left in your refrigerator from the weekend's meals. Hard-boiled eggs, along with anchovies and olives, bring the salad closer to its origin in the south of France.
