Chop up a cucumber.
Chop up some green onion.
Mince in a small clove of garlic.
Add about a teaspoon of salt.
Add about a teaspoon of sugar (Bronte called this Korean candy).
Add about 2 teaspoons of red chili flakes.
Throw in a dash of pepper.
Taste it and see what you think. You may prefer it saltier, or with more garlic. Let it chill a little before you serve it - that's why I put this part at the beginning of this post.
Now that you've got your pancheon ready, you'll want a main course. Among the simplest, yet tastiest, of all the dishes she taught me was...err, this one. I don't think it really has a name. It's kind of like bulgogi, because you make a marinade for your meat and stir fry it with some vegetables, but it's spicy, like dalkgalbi, yet doesn't have so many vegetables in it, and to add to the confusion, although she taught me to make it with pork, I haven't managed to actually do so even once. If you need to call it something, go with gochu seogogi. Spicy stir-fried beef.
