Tart grapefruit gives refreshing flavour to these savoury shortbread cookie bars. Gradually add the food colouring to the glaze, alternating between red and orange, until you get a light coral colour. The tint will intensify as the glaze dries, so stop adding food colouring when it's a touch lighter than your desired shade.

  • Prep time 25 minutes
  • Total time 2 hours & 30 minutes




Cookies: In stand mixer with paddle attachment, or in bowl using wooden spoon, beat together butter, icing sugar, grapefruit zest, vanilla and salt until light and fluffy; stir in flour and thyme just until combined.

Press dough into bottom of parchment paper–lined 9-inch (2.5 L) square cake pan. Using palm of hand, flatten to make smooth even surface. Sprinkle with granulated sugar. Using knife, score surface of dough into 24 rectangles; prick each several times with fork. Refrigerate until firm, about 30 minutes.

Bake in 300°F oven until firm and pale golden, about 55 minutes. Let cool for 5 minutes; cut through score lines. Let cool completely in pan. (Make-ahead: Store in airtight container for up to 1 week or freeze for up to 1 month.)

Topping: In bowl, whisk icing sugar with grapefruit juice. Alternately stir in red and orange food colouring to tint icing coral; drizzle over cookies. Sprinkle with thyme (if using). Let stand until set, about 15 minutes.

Makes 24 cookies.
