Onion Rings

Apple Mostarda

Method

Preparation of Onion Rings

  1. 1

    Slice the Onions

    Peel and slice the large onions into 1/4 inch thick rings.

  2. 2

    Prepare the Batter

    In a mixing bowl, combine flour, cornstarch, baking powder, salt, and black pepper. Gradually whisk in the cider until a smooth batter forms.

  3. 3

    Heat the Oil

    In a deep pan, heat the vegetable oil over medium-high heat until it reaches 350°F (175°C).

  4. 4

    Coat and Fry

    Dip each onion ring into the batter, allowing excess to drip off, and carefully place them in the hot oil. Fry until golden brown, about 3-4 minutes, then remove and drain on paper towels.

Preparation of Apple Mostarda

  1. 5

    Combine Ingredients

    In a saucepan, combine apple cider vinegar, brown sugar, dijon mustard, grated apple, and salt.

  2. 6

    Cook the Mixture

    Bring the mixture to a simmer over medium heat, stirring occasionally until the sugar dissolves and the sauce thickens slightly, about 10 minutes.

  3. 7

    Cool and Serve

    Remove from heat and allow to cool before serving alongside the onion rings.
