I asked the list about FF and Hashbrowns at McDonalds and received the
following responses:
1. Check the listing at each restaurant that lists the ingredients.
2. Both Hashbrowns and FF are GF as long as they use a dedicated fryer
(which most do).
3. 3 to 6 months ago McDonald's changed ingredients in their Hashbrowns are
now GF; the FF have always been GF.
Thanks.
