Listings show grease cups are made from silicone or enamel-coated metal; product details list the container material as either silicone or metal.
Common capacities shown in listings are 8 ounces (1 cup) and 16 ounces (2 cups).
Many grease cups include a removable strainer that sits on top and catches small bacon bits while allowing the strained grease to be poured out cleanly.
Listings describe silicone grease cups as heat-resistant up to 500°F, allowing them to hold hot grease without melting.
Grease cups let grease cool and solidify so you can scoop or pour it into the trash or compost instead of down the drain. Listings also suggest straining and saving cleaned grease for later use to avoid pouring it into pipes.
They are described as sturdy, durable, BPA-free, heavy-duty, non-stick, and resistant to stains and odors.
