This homemade slaw has loads more flavor than any store-bought version.
In a food processor fitted with the shredding disk (or on the large holes of a box grater), grate carrots. In a large bowl, whisk together yogurt, vinegar, mustard, sugar, and onion; season with salt and pepper.
Add carrots, cabbage, and dill to bowl; toss well. Top mixture with a plate that fits inside the bowl; weight with a heavy object. Let sit at room temperature 20 minutes before serving.
Choose carrots that are smooth and firm, free of cracks, and deep orange in color. If the leafy tops are attached, they should be moist and bright green, with no signs of wilting.
