In a small bowl, submerge the raisins in boiling water and let them sit 15 minutes to rehydrate and become plump. Drain the raisins and set them aside.
Toast the cumin seeds in a small, dry skillet over medium heat. After about 3 minutes of swirling the seeds in the pan to toast them evenly, they should begin to smell fragrant and a couple seeds should pop. Immediately remove the seeds from the heat and dump them into a spice grinder or mortar and pestle. Add a pinch of salt, then grind the seeds into a fine powder.
Trim then peel the carrots. Using a mandoline, sharp knife, or Y-shaped peeler, thinly slice the carrots lengthwise into ribbons. Cut the thin slices into matchsticks. If this is too much effort, simply slice the carrots into thin coins or grate them in a food processor.
In a large bowl, add the carrots, grated ginger, grated garlic, minced jalapeno, chopped cilantro, cumin power, and plumped raisins. Add 3 generous pinches of Kosher salt and toss to combine. Dress lightly with the shaken and rested lime vinaigrette, then toss again to combine. Taste the salad and adjust the seasoning as desired.
Refrigerate the salad for at least 30 minutes to let the flavors mingle together. The salad will keep, fully dressed, about two days in the fridge and is even better the second day.
When ready to serve, toss to redistribute everything, then plate the salad on a large platter or in a bowl, garnished with a few sprigs of cilantro if desired.
