Bring stock to the boil in a medium saucepan over medium heat. Reduce heat and simmer, covered, until required. Slice asparagus diagonally, keeping tips in one piece. Set aside.

2

Lightly spray a large saucepan with oil and heat over medium heat. Cook onion, celery and fennel seeds, stirring, for 4-5 minutes or until softened. Add garlic and cook, stirring, for 1 minute or until fragrant.

3

Add barley and stir to coat. Reduce heat and add 1L (4 cups) of the stock, one ladleful (1/2 cup/125ml) at a time, stirring continuously, until all the liquid has absorbed (this will take about 20 minutes).

4

Add asparagus stalks and remaining 1 cup (250ml) stock and cook, stirring, for 10-12 minutes, or until barley is tender. Meanwhile place asparagus tips in a medium bowl. Cover with boiling water for 2 minutes or until bright green and just tender. Drain and set aside.

5

Remove from heat, stir in juice, three-quarters of the rind and chopped mint. Season with salt and pepper. Serve sprinkled with asparagus tips and remaining rind and mint leaves.
