Yes I have plenty of room in my basement When you say Egg Mayonnaise, are you referring to mayonnaise made with just eggs and oil and maybe a touch of lemon juice or vinegar?Yes here in the UK, I can get a small bag of that Hydrated Lime, but she didn't freeze it remember, she put in a normal room or a cold room.
I also looked at making Egg Mayonnaise, I like that and never thought of it before.
