If you have tissue eosinophilia, the level of eosinophils in your bloodstream is likely normal. Blood eosinophilia may be detected with a blood test, usually as part of a complete blood count. A count of more than 500 eosinophils per microliter of blood is generally considered eosinophilia in adults. A count of more than 1,500 eosinophils per microliter of blood that lasts for several months is called hypereosinophilic syndrome. Causes.
Preheat the oven to 400 degrees F (204 degrees C). Place the short ribs on a baking sheet, season with salt and pepper, and roast in the oven for 15 minutes. Remove the ribs from the oven, and then reduce oven temperature to 300 degrees F (149 degrees C).
Bake the ribs: Set the oven to 300Â°F. Move the ribs to an oven rack in the middle of the oven. Roast for 2 1/2 to 3 hours for spare ribs or 1 1/2 to 2 hours for baby back ribs. Halfway through cooking, cover the ribs with aluminum foil to protect them from drying out. Brush with barbecue sauce: About 30 minutes before the end of cooking, brush the ribs with barbecue sauce, re-cover with foil, and finish cooking.
