Quick-pickled onions

Garnish & seasoning

Method

Quick-pickled onions

  1. 1

    Slice the onion

    Peel the red onion and slice it very thin (use a sharp knife or a mandoline) into rings or half-rings so they pickled quickly and layer easily on the sandwich.

  2. 2

    Make the quick brine

    In a small saucepan combine 60 ml white vinegar, 60 ml water, 1 tbsp sugar and 1 tsp salt. Warm gently over low heat just until the sugar and salt dissolve (do not boil). Remove from heat.

  3. 3

    Pickle the onion

    Place the sliced onion in a heatproof bowl or jar. Pour the warm brine over the onion so all pieces are submerged. Let sit at room temperature for at least 10 minutes (can sit up to 1 hour). If making ahead, cover and refrigerate; bring back to room temp before assembling.

Sandwich assembly

  1. 4

    Toast the bagels

    Split the 2 bagels and toast them to your preferred level of golden-crisp. Keep them warm while you prepare the spread and toppings.

  2. 5

    Prepare the goat cheese spread

    In a small bowl, soften 113 g goat cheese by stirring with 1 tbsp extra-virgin olive oil and the juice of 1/2 lemon (about 1/2 tbsp). Whisk or mash with a fork until smooth and spreadable; taste and adjust with a small pinch of salt if needed.

  3. 6

    Drain the capers

    Place 2 tbsp capers in a small sieve and rinse briefly under cold water to remove excess brine, then drain well — this reduces overpowering saltiness on the sandwich.

  4. 7

    Assemble each bagel

    Spread a generous layer of the lemon-goat cheese on each toasted bagel half. Layer smoked salmon (about 60 g per serving half, 120 g total across both bagels), then distribute the drained capers evenly on top of the salmon. Add several pieces of the quick-pickled onion on each sandwich (use tongs or a fork).

Garnish & serve

  1. 8

    Finish and season

    Scatter 2 tbsp chopped fresh dill over the stacked toppings, finish with a light grind of black pepper (about 1/4 tsp total split across sandwiches) and, if desired, a quick drizzle (about 1/2 tsp) of extra-virgin olive oil or a small squeeze of the remaining lemon. Taste and adjust — add more pickled onion or capers as desired.

  2. 9

    Serve

    Serve immediately while bagels are warm and goat cheese is creamy. Leftover pickled onions keep refrigerated up to 1 week; assemble smoked-salmon sandwiches just before serving for best texture.
