It usually takes 3 to 6 days for a person to get symptoms of hand-foot-and-mouth disease after being exposed to the virus. This is called the incubation period.
Preheat oven to 400 degrees F. Cut off the brown ends of the Brussels sprouts and pull off any yellow outer leaves. Mix them in a bowl with the olive oil, salt and pepper. Pour them on a sheet pan and roast for 35 to 40 minutes, until crisp on the outside and tender on the inside. Shake the pan from time to time to brown the sprouts evenly. Sprinkle with more kosher salt (I like these salty like French fries), and serve immediately.
Place a large knob of butter in a hot frying pan. Add brussels sprouts, toss to coat, then pour over Â½ cup stock. Cover the pan and let the sprouts cook for 4-5 minutes or until just tender. Place boiled brussels sprouts in a gratin dish. Pour over a white sauce and sprinkle with your favourite melting cheese and a cup of fresh breadcrumbs. Bake in a 180Â°C oven for 30 minutes, or until bubbling and golden.
