Use coarse salt and black pepper, do not use the white pepper, it is hotter than black. Use these individually and eyeball the coating for each. Sugar can help reduce the heat so either put it on before cooking or use a sweet sauce later.
I have the same conditions at my house half my family can hardly tolerate even black pepper and like myself the rest like it at least warm, so I feel your pain.
