What herbs and spices are suitable to use in soups?

Soups can benefit greatly from the addition of herbs and spices, which may offer a variety of flavours and complexity. Here are a few herbs and spices that pair well with soups:

1. Basil: Basil's fresh, sweet, and slightly peppery flavour works well in broths, tomato soups, and many Italian-inspired soups.

2. Bay leaves: Bay leaves are well-known for lending their subtle warmth and herbal flavour to dishes. Typically added to soups at the start and removed before eating.

3. Oregano: This Mediterranean herb has a robust, slightly pungent flavour with hints of mint. It's excellent for tomato soups, bean soups, and vegetable soups.

4. Thyme: Thyme is a versatile herb that complements stews, bean soups, and chicken soups. It has a slightly earthy and slightly lemony flavour.

5. Rosemary: This herb has a slightly bitter and pungent flavour. It's good in vegetable soups, bean soups, and stews.

6. Marjoram: This mild herb is often used in place of or in combination with oregano. It works well in tomato soups, bean soups, and vegetable soups.

7. Celery: Celery leaves and seeds can give a fresh, vegetal kick to soups and vegetable broths.

8. Paprika: Paprika adds a mild or bold flavour, along with a slight bitterness, to soups.

9. Cumin: Cumin's warm and slightly smoky flavour is great in soups with a Middle Eastern or Indian twist.

10. Chilli powder: Chilli powder can add a touch of heat and spice to soups.

11. Coriander: Coriander seeds and leaves can bring a citrus-like flavour to soups.

12. Ginger: Ginger's warm and spicy flavour pairs well with Asian and vegetable soups.

13. Garlic: Garlic adds a potent and savoury flavour to many types of soups.

14. Onion: Onion is crucial for providing a flavour foundation to many soups.

15. Fennel: Fennel's slightly sweet, anise-like flavour lends itself to vegetable soups, seafood soups, and broths.

When using herbs and spices, start with small quantities and gradually increase the amount based on your taste preferences and the soup recipe. Remember, the secret to a flavourful soup lies in the balance of ingredients and the harmony of flavours rather than overpowering the dish with a certain spice or herb.
