The trick to making gaufrettes is to use the right potatoes–floury varieties are best. If you don’t have a mandoline with a crinkle-cut attachment, simply prepare plain-cut chips.
Ingredients
Aïoli
Summer-vegetable tartare
Method
1.Working with one potato at a time, run potato over a mandoline with crinkle-cut attachment in one direction, then turn potato 90 degrees and run potato over again, slicing to create a waffle effect. Continue to slice and turn potato every second slice so that each slice is a lattice chip. Transfer potato slices to a large bowl, then pour over boiling water and leave to soak for 5 minutes. Drain chips, then arrange in a single layer on paper towels and leave to dry.
2.For aïoli, blend garlic, egg yolks, mustard and vinegar in a small food processor until combined. With motor running, gradually add oil, a few drops at a time at first, then in a thin, steady stream until emulsified and thick (be careful not to add the oil too quickly, as mayonnaise will split). Season with pepper and lemon juice to taste.
3.Preheat oil in a saucepan to 160°C. Deep-fry potato gaufrettes in batches, turning occasionally, until light golden and crisp (2-4 minutes; be careful, hot oil will spit). Drain on paper towels, then sprinkle with sea salt flakes.
4.For summer-vegetable tartare, combine ingredients in a bowl and stir through a little aïoli to coat (you may only need a
few tablespoons; remaining aïoli will keep refrigerated for up to 1 week). Season to taste, garnish with nasturtium flowers and serve with potato gaufrettes.
