    So good!

    Best tartar sauce recipe I’ve ever made. Thank you!

    (My fish seemed to be done after 3 mins. Breading looked ready to go. But I followed the cooking time on the recipe and felt like the fish was overcooked. This may have been because the suggested temp of 350-375 was hard to maintain.)

    I’m making this for Good Friday – it looks delicious. I’m just confused, do i add the egg & beer to the flour, cornstarch mixture. I’m doing it in the airfryer – and you say to dip in flour again after the batter.
    Thank you

    Looking forward to making this for Good Friday. Meatless supper.
    I’m just looking for clarification – do i add the beer & egg to the flour, cornstarch, spice mixture? I’m using my air fryer and you say to dip back in the flour before frying.
    Thank you

    Personally, if I’m going to go through all that trouble and expense I’d make fish and chips instead.
