3 T. distilled white vinegar
1 tsp. black peppercorns
4 artichokes (each about 4 in. wide; 3 lb. total)
1/2 C. drained extra firm, firm, or soft silken tofu
2 T. lemon juice
2 tsp. extra-virgin olive oil
1/2 tsp. dry mustard
Salt and fresh-ground pepper

Fill a 6- to 8-quart pan halfway with water. Add vinegar and peppercorns; bring to a boil over high heat. Meanwhile, slice about 1 inch off tops of artichokes; discard tips. Trim stems flush with bottoms. Pull off and discard small leaves from bottoms. With scissors, cut thorny tips from remaining outer leaves. Add artichokes to water and simmer, covered, until bottoms pierce easily, 30 to 35 minutes; drain. While artichokes cook, make lemonnaise. In a blender or food processor (a blender produces the best results), whirl tofu, lemon juice, oil, and mustard until smooth. Season with salt and pepper. (If making ahead, chill airtight up to 1 day; stir before using.) Serve artichokes with sauce for dipping.

Varying your dunk sauce: For variations on lemmonaise, add ingredients to the basic recipe and whirl in a blender or food processor until smooth.

Aioli: Add 1 clove minced garlic.
Caper-anchovy sauce: Add 2 tsp. drained capers and 1 1/2 tsp. anchovy paste.
Chili-cilantro sauce: Instead of lemon juice, use 4 tsp. lime juice. Add 1/2 to 1 stemmed fresh serrano chili and 1/3 C. packed fresh cilantro.
Dried-tomato sauce: Add 1/4 C. dried tomato halves (not oil-packed).
Green sauce: Add 1 C. each lightly packed spinach leaves and parsley, and 1/2 C. chopped green onions.
Madeira sauce: Add 2 T. each madeira and minced chives.
Orange-coriander sauce: Use only 1 T. lemon juice. Add 4 tsp. orange juice and 1/2 tsp. each ground coriander and grated orange peel.
Tamari-sesame sauce: Substitute Asian (toasted) sesame oil for olive oil. Add 1 1/2 tsp. tamari.
