Those are the snack sized doormice - teh glis glis are much much bigger - about guinea pig sized. I expect any regular guinea pig recipe will do nicely.
Like doormice , in france they are very partial to tiny birds called ortolans. I beleieve it is illegal now to hunt them as they ate so many. They are drowned in wine, and then baked whole, and you eat the whole bird spitting out the beak and legs, plus any bony bits. Wit a towel over your head to intensify the aroma and avoid causing offence to others.
