My brothers and I would line up in the kitchen at night for our delicious doses of “white stuff” as it was affectionately known in our family. We loved it!
I did have a chuckle reading Margret and Bill's comments about how good Petrolagar tasted. I though I was the only weird one that loved this stuff. My mother would give us a tablespoon of it to keep us regular, but I would frequently sneak into the bathroom cabinet and take swigs like an alcoholic addicted to goon. hahahah
Does anyone know if there a near perfect substitute for this miraculous product? My Mother gave it to us as kids. Second best was a product that is still on the market with a drop of one name. Originally it was called 'Mother Fletcher's Castoria'........I still find that name funny. Apparently it is still marketed by the name 'Fletcher's Castoria'. Also, I must comment on 'Bill's comment above, regarding the 'good taste'. We kids loved it too!!! Sennacot is now the next best thing.
This thick white mixture was so good to the taste that my sister and I once ate a whole bottle together. A real party that lasted for days after!
