buying lamb shoulder
You can buy lamb shoulder from a variety of places, depending on where you live and what's available in your area. These places include:-
- Large supermarkets.
- Your local butcher.
- Ethnic grocery stores, particularly those specializing in Middle Eastern, Mediterranean, or Greek foods, often have a good selection of lamb.
- Farmers market.
- Online meat retailers.
cooking using parchment paper
I recommend you do not skip on using parchment paper for the following reasons:-
Wrapping the lamb in parchment paper before cooking helps to seal in moisture. As the lamb cooks slowly, the parchment paper traps steam and prevents the juices from evaporating, keeping the meat moist and tender.
The parchment (baking) paper helps distribute the heat more evenly around the lamb, resulting in consistent cooking.
refregerating leftovers
Allow the meat to cool to room temperature before storing. To prevent bacterial growth, do not let it sit out for more than 2 hours.
Store in the refrigerator for 3-4 days.
freezing instructions
To freeze, wrap leftover kleftiko in alaluminum foil or place it in an airtight freezer-friendly container.
Label the container with the best-by date so you can keep track of storage time and freeze for 6-9 months (see USDA lamb storage instructions here).
When ready to eat, thaw the meat in the refrigerator if it was frozen and reheat it in the oven or microwave until warmed through.
If using an oven, cover it with foil to prevent drying out.
