Although heirlooms get all the glory this time of year, not all tomato hybrids are inherently evil. Take the insanely sweet Sun Gold variety, for example. No less a member of the tomato cognoscenti than Mario Batali is a big fan.

In the steamy swelter of summer, when the thought of turning on the oven is anathema, there are few things more refreshing than sweet, juicy watermelon and cool, crunchy cucumber.

With zucchini and its globular, elongated, and crookneck ilk flooding the market, there’s no such thing as too many summer-squash recipes.

Sour cherries are compulsory for pie, but sweet ones like Bing and Rainier do well poached, especially in the company of classic companions like port and balsamic vinegar.

Fresh summer blueberries are a glorious thing. And so, it hardly needs saying, is pie.

Perhaps the subtlest member of the onion family, chives possess a relatively mild flavor that is a nice addition to salads, edible lavender blossoms and all.

Attention, fromage-loving Joycean scholars: Cato Corner Farm’s Bloomsday cheese aged one year will arrive on schedule next week at Greenmarket.

Sorrel, the arrowhead-shaped herb and member of the buckwheat family that’s prized for its inherently tart, lemony flavor, is traditionally used in cream soups and fish sauces.

While ramps get all the Greenmarket glory this time of year, green garlic (a.k.a. spring garlic, young garlic, and baby garlic) is no slouch in the pungent-flavor department.
