When You're Making Carbonara
Trusty and useful, frozen baby peas are available year-round, can be stashed in your freezer for months, cost about $2.29 for 16 ounces (compared to $5 for fresh), and tend to taste even sweeter than fresh (there's such a short window of time for fresh ones to be delicious, that usually, by the time they get from the farm to your store, they're starchy and flavorless). Pettry uses them at home, when she's making pasta (such as classic carbonara), or she tosses them into salads when they've thawed but are still cold.
