If you’re using a food processor, use the grating blade to shred the potatoes, carrots, and onion, and transfer to a large mixing bowl. This may be done in two or three batches, depending on the size of your machine.
If you’re shredding by hand, use a box grater to shred the potatoes and carrots. Dice the onion as finely as possible. Transfer to a large mixing bowl.
Add the ginger, potato starch, curry, cumin, salt, and red pepper flakes to the mixing bowl. Use your hands to mix everything in with the potatoes, carrots, and onion. Keep mixing until the potatoes have released some moisture and the starch is dissolved, about 2 minutes.
Fold in the peas. Add the matzoh meal and mix well. Set aside for about 10 minutes. The mixture should be somewhat loose but hold together if pinched. If it seems excessively wet, add a little extra matzoh meal.
In the meantime, preheat a large cast iron pan over medium-high heat. Have ready some brown paper bags or a baking sheet lined with paper towels for draining the oil from the latkes. Add about ½ inch of oil to the pan. While the oil heats, form some latkes.
With wet hands (so that the mixture doesn’t stick), roll the dough into golf balls, then flatten into thin patties. Get about six ready before you start frying.
The oil is hot enough when you drop in a pinch of batter and bubbles rapidly form around it. If it immediately smokes, then the heat is too high and you should lower it a bit. If the bubbles are really lazy, just give it a few more minutes or turn up the heat a bit.
Working in batches, fry the latkes until golden brown on one side, about
4 minutes. Flip over and fry for another 3 minutes.
Transfer the latkes to the lined pan to drain, sprinkle with a little salt, flip, and sprinkle with salt again, then proceed with the remaining latkes. Serve warm, with the chutney.
