Ancestors

[irondoe]

So, for the people that do ancestor worship, especially those of you from a European background, what kind of things do you offer them (besides fresh water)? Is it strictly stuff they liked during life, or a set of things you offer to all ancestors, or a mix?

I'm asking from a Euro background because that's my own background and I do not want to take practices that aren't mine. Looking especially for Celtic, Northern European, and Eastern European practices (but not specifically Slavic or Scandi)
