3/4 C. apple cider vinegar

1-1/2 tsp. coarsely ground black pepper

2 tsp. kosher salt

1/2 tsp. sugar

3/4 tsp. English-style dry mustard

1/4 tsp. dried hot red pepper flakes (or to taste)

1/4 tsp. mustard seeds

1/4 tsp. coriander seeds

1 C. olive oil

3 large garlic cloves, chopped

1 bay leaf

1-1/2 lb. large shrimp, shelled and deveined

1 medium onion, halved lengthwise and thinly sliced

1 lemon, thinly sliced

2 Tbsp. fresh dill or Italian parsley

1 thin baguette, cut into 1/2″ slices and lightly toasted in a 350 F oven for 2-3 minutes on each side

 

Whisk together the vinegar, pepper, salt, sugar, mustard, red pepper flakes, mustard and coriander seeds in a bowl and add the oil in a stream, whisking. Whisk until emulsified, then stir in the garlic and bay leaf. In a large pan of boiling lightly salted water cook the shrimp for 1-2 minutes or until they turn pink and are cooked through. Drain them well and add them to the marinade. Let the mixture cool slightly, then stir in the onion and lemon slices. If desired cover and chill overnight. Stir in the minced dill or Italian parsley and transfer to a portable container. To serve, spoon on baguette slices or dip slices in the mixture and scoop up the shrimp.
