Reddit reviews Secrets of Colombian Cooking, Expanded Edition

If you want a physical book, I'm fond of Secrets of Colombian Cooking (ISBN 0-7818-1025-6). 90% of what I know from Colombian cooking comes from my mother, 9% from her translating Gran Cocina Colombiana, and 1% from this book, but my very Colombian aunt swears by it. I can understand your predicament, my Spanish is atrocious, too. You can get it on Amazon here. The one thing I would note is that some ingredients (like masa harina / yuca harina) can be hard to come by, depending on where you live in the States.
