(Not being Jewish, I don't feel entitled to call any food I produce "latkes" so these are latke-ish things.)
4 very small (baby) potatoes
1 oz cheddar cheese
Just the green part of less than one green onion, snipped with scissors
freshly ground black pepper (to taste)
Lots of oil
Shred the potatoes and cheese together, add the egg and beat well. Add the green onion and pepper, beat. In a decent pan, heat about 3/4" of oil. Drop in SMALL amounts of the "batter" and fry, flipping once, until golden brown. Remove, drain on paper towels.
Top with: home made mustard (no I will not give you the recipe! this one is my secret, but it's easy to develop your own recipe, basically you just need mustard seed and vinegar, then everything else -- other spices, salt, honey, etc. -- is up to you), or sour cream, or plain yogurt, or just salt.
