The silkiness of the of the mild butter (or Boston) lettuce pairs well with the spicy lemony flavor of the sorrel, sweet bite of a red onion freshly pulled from the ground, and tangy Macintosh stewed with fall spices. All are currently in season at New York’s Greenmarkets, so take advantage of this recipe before first frost. Paired with soup and some hearty, chewy country bread, this is the perfect Fall meal for still-summer weather.
