1. Leave meat on counter for approximately one hour.
2. Meanwhile, heat olive oil in a large frying pan. Add onions and honey. Lower heat and sauté for 45–50 minutes, stirring frequently to separate the onion rings, until onions are caramelized. (This can be done a day before or even a while in advance and frozen. Defrost before using.)
3. Place onions into a large (six-quart) pot and place roast on top. Drizzle with olive oil. Sprinkle with kosher salt, pepper, and instant coffee. Rub all over the meat.
4. Squeeze oranges and clementine. You should have one cup of fresh juice. Pour the juice around the roast. Add the blended tomato and grated sweet potato, distributing them all around the roast. Add the garlic cloves.
5. Bring the pot to a boil. Lower heat to very low (you should see bubbles in the liquid) and continue cooking for four hours, rotating the meat every hour.
6. Remove the meat from the pot. Refrigerate and slice when cool. Store gravy separately.
Sounds so cool and different! I would love to try for pesach! Can it be baked?
You can for the meat part, but the first few steps need to be done in a pot.
