Re-freezing thawed preserves. Is this safe?
I have home-made freezer jams and frozen pesto.
I'd like to take them as gifts to families & friends in Europe. During overnight flight (in the summer) destination, these preserves will likely thaw. I will meet some families & friends 2-3 weeks after my arrival. Is it alright to re-freeze them upon my first arrival? Are they safe for consumption? Appreciate any advice.
