Not eat, but drink. When I’m not feeling well (eg., fever, flu, nausea), I always like to drink a concoction my grandmother used to make for me as a kid whenever I got sick. It’s Coca-Cola with fresh ginger.
My grandma heated the Coca-Cola in a saucepan, added a lot of chopped fresh ginger (perhaps 1 to 2 full tablespoons), and boiled the concoction. It’s a good remedy for fever and nausea. However, it’s very spicy and not to everyone’s liking.
Drink the hot Coca-Cola/ginger drink, then wrap yourself with a warm blanket. In an hour or so, you’ll sweat it out and feel much better.
To eat, I like to eat steamed egg custard, but it’s not the Western-style sweet custard most people here are familiar with. It’s Japanese egg custard. You beat three eggs with a cup of chicken broth, then steam it in a bowl until it’s soft and smooth, almost soup-like. Add some fresh grated ginger on top and it’s done. I love the savory taste of the custard, and it really hits the spot and soothes your stomach when you’re sick——it also replenishes the lost salt in your body.
