Tabasco is not recommended but I know many use this without problems.
The cinnamon and nutmeg - wait until week three then check to see it doesn't take you out of ketosis. Nutmeg is lovely on top of the vanilla or banana. Banana mousse made from the Tetra with nutmeg on the top tastes just like egg custard.
lg of curry powder can be added to the soups, again with some people it can make them hungry.
Never add anything salty so no soy sauce or worcestershiresauce but any pepper is okay.
