Sweet-sour vegetable pickles

Searching for more pickle recipes for my podcast, I found this in one of my Japanese cookbooks. It’s quite simple.
Sweet-Sour Vegetable Pickles

1/4 cauliflower
1 cucumber
2 onions, small
4 radishes
1 cup water
1 cup white wine vinegar
3 Tbsp sugar
1/2 tsp salt
1 laurel leaf
1 dried chili pepper
Trim the cauliflower into florets. Blanch. Peel the onions, blanch, then cut in half. Cut the cucumber in to 4 cm sticks. Trim the radishes.
Mix the remaining ingredients and pour over vegetables. Refrigerate for at least three hours. Keeps up to 1 week.
