ReaLemon Single Serve Lemon Juice Packets, 4 g, 200 Count

Two hundred individually sealed packets of ReaLemon juice, 4 g apiece. That is about a teaspoon, close to what you would squeeze out of one wedge from a lemon cut into eighths. The packets are shelf stable, so a case lives in a cupboard until one is torn open.

The point of a packet is the portion. Diners, catering vans, hotel breakfast bars and quick-service counters set them out beside iced tea urns, fish fry baskets and oyster plates so each guest doses their own. Offices and break rooms keep them by the hot water and the tea bags for the same reason.

At home they give you a wedge's worth of lemon on demand: a squeeze into tea, over grilled salmon or fried fish, into a dressing you are whisking for one, or into a glass of water. They travel well in a lunch bag, a carry-on or a hotel room.
