Fennel Seeds — what are they and why use them in BBQ?
Quick answer: Fennel seeds have a sweet, anise-like aroma. In a BBQ rub, they can add a warm, aromatic flavour to chicken, pork or vegetables, for example. They are a distinctive flavour in our Italian-inspired Toscana Fire.
Fennel seeds are used in Italian dishes and spice blends, among other cuisines. On the BBQ, they can also work well with smoky or spicy flavours. Below, we explain how to use and store whole or ground fennel seeds.
What are fennel seeds?
Fennel seeds is the culinary name for the dried fruits of Foeniculum vulgare, the fennel plant. Their aroma resembles anise, but fennel seeds and star anise are different spices. Perceived intensity depends on the product, freshness and dose, among other factors.
You can use fennel seeds whole, crushed or ground. Ground fennel spreads more evenly through a rub; whole or coarsely crushed seeds also add texture. Fennel features in Italian sausages such as salsiccia and some salamis, but it is not compulsory in every Italian dish or Tuscan preparation.
What do fennel seeds taste like?
Fennel seeds generally have a warm, sweet, anise-like aroma. This can complement smoked paprika and black pepper. Aromatic sweetness does not mean fennel automatically caramelises or gives meat a particular colour. Heavy toasting or burning can make it unpleasantly bitter.
Whole seeds give concentrated flavour accents and a noticeable bite. Crush or grind them for a finer distribution. In either a dry rub or a marinade, choose the form to suit your dish; grinding is not compulsory for every rub, and whole seeds are not always stronger.
Why use fennel seeds in Toscana Fire rub?
Fennel seeds are a distinctive flavour in Toscana Fire rub. Along with smoked paprika, allspice and cayenne, they form the four signature flavours we highlight for this Italian-inspired blend of our own. This is not a complete ingredient list: check the current packaging for allergens and dosing as well.
We do not list coriander here as an ingredient in Toscana Fire. To compare spices for a blend of your own, see the separate guide to ground coriander.
Fennel can give chicken, pork or vegetables an aromatic accent. How prominent it becomes depends on the dose and dish. The rub is not proof of a traditional Tuscan recipe and does not guarantee golden skin or a juicy result.
How should you store fennel seeds?
Keep whole and ground fennel seeds dry, dark and well sealed, away from heat and steam. Follow the date and storage instructions on the packaging. There is no universal three-year shelf life for whole seeds or twelve-month period after opening for ground fennel.
Under comparable storage conditions, whole seeds generally retain their aroma longer than ground fennel. Grind a small amount just before use if you prefer. Use clean, dry utensils and keep the stock away from raw meat. Toasting cannot make uncertain storage or visible mould safe.
Using fennel seeds on the BBQ
Start with a small amount and build the flavour in a test portion. One part fennel to four parts paprika can be a starting ratio of your own choosing, but it is not a fixed BBQ rule or the recipe for Toscana Fire. Note whether you are measuring by weight or volume; these do not automatically give the same result.
For your own blend, try combining it with smoked paprika, garlic powder and black pepper. Chicken, pork tenderloin, sausage and grilled vegetables are possible uses. Account for the full seasoning, salt and any allergens in all ingredients.
You can briefly dry-toast whole fennel seeds in a pan over controlled heat. Keep them moving and stop when fragrant, before they darken or smoke. One to two minutes is only a rough guide: the pan and heat make a difference. Let them cool before grinding. Toasting is optional, and blending does not improve a burnt batch.
Use controlled heat on the BBQ too: spices can burn even without added sugar.
