This is an apple and cheddar salad and I would humbly argue an excellent one, the best I’ve ever made, but this recipe is also an excuse for me to share a few of the best tricks I keep up my sleeve (I always wanted to be a cook who said things like that, when what you might actually find is a lost piece of popcorn) to make the kinds of complex salads I can never resist on a cafe menu at home as simply as possible. Because we deserve to have fancy, cool, crunchy, dynamic, and gorgeous salads at home, even if we do not live a life that allows us to afford fancy salads made by others on a regular basis.
Heat oven to 400°F.
Start the dressing: In a medium bowl, combine shallot and apple cider vinegar and set aside while you make the crispy stuff.
Make cheddar crisps and sugared almonds: Line a large (half-sheet size) rimmed baking sheet with parchment paper. Scatter cheddar evenly over half the parchment, in about a 8×12-inch, 1/4-inch thick rectangle. Sprinkle with a little cayenne or black pepper, if you wish.
In a colander, rinse almonds under cold water (yes, really!) and shake off excess liquid. In a bowl, toss wet almonds with powdered sugar, salt, and 1/4 teaspoon cayenne until evenly coated. Spread on second half of parchment-covered baking sheet in a thin, even layer, leaving an inch around it bare so it can spread.
Bake almonds and cheddar together for 4 to 9 minutes, until the cheese is melted into a lacy, evenly deep golden brown crisp and the almonds are dark at the edges and lightly golden throughout. Please hear me on this: Watch it closely. Both the cheddar and the almonds will go from not-yet-golden to perfectly bronzed to burnt in what feels like a one-minute period. Check it at 4 minutes, then every minute or two thereafter until the pan is just right. Remove and let cool while you finish the salad.
Finish the dressing: To the shallots and vinegar in the bowl, whisk in dijon, mayo or yogurt, then drizzle in olive oil, whisking the whole time. Season dressing with salt and lots of freshly ground black pepper.
Assemble: In a large wide bowl or salad plate, toss greens with 2/3 the dressing to start, then tasting and adding the rest if you wish. Arrange the apple over the greens, fanning out slices. Break off clustered of almonds from the baking sheet and scatter them over the salad. If the cheddar crisp seems very oily, you can blot it with a paper towel, before tearing or cutting it into large bite-size pieces and scattering them over the salad. Season the salad with additional salt and pepper and serve right away.
