I made the Spanish onion potato soup tonight and must thank you for a wonderful recipe. The spices are right on. I used the stove top to cook it and let the onions cook up bit before adding everything else. had to add garlic as well. Well balanced and with bread just delicious.
Thanks.

Elyce
what can I substitute for sherry?
Martha McKinnon
Hi Elyce, I’ve never made this recipe with anything other than the sherry. I did a little online research and one suggestion that sounded good was diluted apple cider vinegar. You might want to try 2 tablespoons apple cider vinegar and 2 tablespoons water. (https://tastessence.com/sherry-substitute) Hope this helps.
