Potato latkes with smoked salmon and horseradish crème fraîche

Method

1. Combine all the ingredients for the horseradish crème fraîche in a small bowl, then season and set aside (or see make ahead).
2. Put the grated potatoes in a large bowl of salted water and swirl with your hands to remove some starch. Drain and rinse under cold running water, then put on a clean tea towel with the grated onions. Gather the towel around and squeeze as hard as you can to extract the moisture (it helps to rest the towel on the side of the sink and use your weight to press down). Transfer to a large bowl, then mix in the eggs and salt.
3. Put the oil in a large sauté pan and heat until a little of the mixture sizzles instantly when dropped in. Using a soup spoon as a size guide, gather up dollops of the mixture and squeeze together in your hands to form into a round.
4. Working in batches, carefully drop in each one and fry for 3-4 minutes on each side until golden, crisp and cooked through. Remove with a slotted spoon. If you’re serving immediately, keep the cooked ones warm in a low oven while you do the rest. If not (see make ahead), drain them on a plate covered with kitchen paper as you go.
5. Serve with the crème fraîche and salmon, with lemon wedges.
