As the days get longer and warmer, and winter gives way to spring, we find ourselves performing annual rituals: we put away our heavy coats, pull out our April showers-ready umbrellas, deep-clean our houses, and open up our windows for a breath of fresh air. The culinary transition is even more exciting: the fresh produce selection at the market starts to show new signs of life, seafood becomes sweeter, herbs become brighter. Stock up on spring essentials — fava beans, salmon, basil, peas —and show them off to their best advantage in one of the world's most popular (and versatile) starches: pasta.
