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.
Bon Appetit recommends parboiling PORK ribs, and pre-roasting BEEF ribs (dredged in flour, paprika, salt & pepper) for about 45 min before roasting. Then, I put either one on a baking sheet (with a dry rub), covered with foil, and slow roast at 250-300 for about 2 hours.
