Is it safe to eat expired hollandaise sauce mix

I have a really old packet of McCormick Hollandaise sauce mix - it's 5 years expired. Is it safe to use and eat? Main ingredients are Wheat starch, maltodextrin, egg solids, soy lecithin, etc..
Best Answer
If it's a powdered mix, it's still powder (not clumped) and the pack is sealed, I'd go for it. Dried foods here are most likely to have a best before date, rather than a use by (real expiry) date. If it's clumped or the packet is damaged it may have absorbed water which wouldn't be good. It's possible that the flavour will have deteriorated a little. For example, powdered egg keeps for 5-10 years, most foods don't have longer than a nominal year on the label.
A wet sauce mix may also keep that long if it's packed in a way equivalent to canning (i.e. sealed then cooked in the packet).
If anything seems wrong about it, avoid it.
