Recipe Notes

Though it would be safe to season the mixture with dried seasonings such as salt, pepper, or dried herbs, it probably is best to leave it plain as the idea is for it to be a flexible base that you can take in a zillion directions with flavouring when you go to use it.

The reason bottled (as opposed to fresh) lemon juice is called for is that it provides a guaranteed acidity level for safety.
