BostongurkaSweet cucumber relish
Every Swedish korvkiosk, from Stockholm's Södermalm to the ferry ports of Gothenburg, offers bostongurka in a squeeze bottle, and most Swedes still put it on their grillkorv with mustard, ketchup and crispy fried onions. Families make their own in August and September, when cucumbers are cheap at the farm stands, and spoon it onto hot dogs at summer barbecues, beside meatballs, into potato salad and onto cheese sandwiches all winter. It is a fine-chopped relish: sweet and sour, golden-yellow from turmeric, with crunch from the cucumber and the soft warmth of mustard seed. Common mistake: skipping the overnight salting; without it the cucumber leaks water and the relish turns soupy and dull. Squeeze the vegetables hard before cooking. It is ready when the vegetables are just tender but still crunchy and the liquid has thickened enough to cling to them. Chef's tip: chop by hand or pulse very briefly in a processor; a purée loses the crunch that makes it bostongurka.
