The Ideal Food

Visiting my aunt, which I've done from time to time since I was wee. Wondering now if she ever slipped me some of this Virol - a prparation of bone marrow that is reputedly "ideal fat food for children and invalids". Doubt it. But it was was advertised extensively and became a very popular cure-all to build up skinny and sickly children after WW2 and right into the 70s. I had a much milder treatment - Dr William's Pink Pills for Pale People. Do you remember these?
