Step 1Cut the cauliflower into florets. Place in a pot filled with water and add the vinegar, peppercorns, salt and bay leaves. Bring to a boil over a high heat. Then, reduce the heat to medium and simmer until the cauliflower is tender for 10 to 12 minutes. Once cooked, take off the heat and pour through a colander. Discard the spices. Set aside to cool down, cut into smaller pieces and then place in a mixing bowl.
