Supper was the main meal of each day. It was eaten near sunset. It consisted of vegetables, fruit, fish, and possibly honey cakes. Sugar was unknown to ancient Greeks, so natural honey was used as a sweetener. Fish was the main source of protein in the Greek diet. Beef was very expensive, so it was rarely eaten.
Also, the duration taken to boil pork ribs depends on their size. Small cuts of pork ribs would take only an hour to become tender, but larger pieces may take about three hours. The estimated time that pork ribs take to boil is about 50 minutes for around 6 pounds of pork ribs.
I've got some meaty pork ribs (shoulder blade) from Safeway. Package instructions say boil first for 35-40 min., then cover with barbeque sauce and grill eight minutes each side. I've roasted (in the oven) these before, both uncovered and wrapped with foil for 2-3 hours on low heat so they would be tender.
