Lo mein (hot bar)
Savory and slightly sweet from the sauce, with soft noodles and whatever vegetables were mixed in that day.
Lens analyzedThis is lo mein noodles scooped from a grocery store's hot food bar, already stir-fried with sauce, vegetables, and sometimes meat, meant to be eaten the same day. Hot bar food is prepared in bulk and held warm for self-serve scooping rather than made to order. Portions and ingredients can vary from one visit to the next, even at the same store.
Where it comes from
Grocery store hot bars grew out of the broader self-serve prepared foods movement in North American supermarkets, offering restaurant-style dishes without a restaurant kitchen. Lo mein, already a familiar takeout dish, became a common hot bar option because noodles hold up well under a heat lamp.
Buying it
Buy it close to when you plan to eat it rather than early in a shopping trip, since hot bar food sits at serving temperature for a limited window before it's pulled.
Storing it
Treat it as a same-day food: refrigerate leftovers right away if you're not finishing it, and eat any extra within a day, since hot bar dishes don't carry the shelf life of packaged deli food.
Keeps about 1 day in the fridge.
