A few things worth knowing.
How long does lamb shoulder take to thaw?
For this 1 lb case, allow 24 hours using the selected method. Plan extra refrigerator time if needed.

No. Use a refrigerator at 40°F or below, cold water with the food in a leakproof package, or a microwave following its instructions.
How often do I change cold water?
Every 30 minutes, keeping the package submerged. Cook immediately when thawed with cold water or a microwave.
Can I refreeze thawed food?
Food thawed in the refrigerator may be refrozen before cooking, though quality can decline. Food thawed in cold water or a microwave must be cooked before refreezing.
