Few meals can beat a Christmas dinner and it’s all down to hidden chemistry

Examples of Christmas Spices and herbs:

Cinnamon – Cinnamaldehyde is the primary compound responsible for cinnamon’s flavour and aroma. It’s a phenylpropanoid with antimicrobial and antioxidant properties.

Nutmeg – Safrole is present in small amounts; it has a sweet, spicy aroma and eugenol contributes to nutmeg’s warm, clove-like notes.

Ginger – Gingerol is the primary compound responsible for ginger’s pungent, spicy flavour. It’s structurally similar to capsaicin (found in chili peppers) and piperine (in black pepper).

Cloves – Eugenol is the primary aromatic compound in cloves, giving them their strong, spicy, and slightly sweet scent. It also has antiseptic and anaesthetic properties.

Sage – Thujone is a monoterpene that gives sage its slightly bitter and camphor-like aroma and camphor adds to the herb’s woody, herbal aroma.

Chemistry explained:

The compounds responsible for the flavours and aromas of Christmas spices belong to various classes of organic molecules, including phenols, aldehydes, terpenes, and ketones. These molecules interact with taste receptors on our tongue and olfactory receptors in our nose. For example, cinnamaldehyde activates receptors for warmth and spice, while eugenol’s complex structure induces a sweet taste.

Some of these molecules have secondary benefits, such as antimicrobial or antioxidant properties, which historically made spices valuable not just for flavour but also for food preservation and medicinal uses.

 

What are these spices used for?

The spices and herbs are used in an array of Christmas confectionaries and treats including:

Mince pies – A blend of cinnamon, nutmeg, and cloves gives these classic treats their warm, spicy aroma.

Mulled wine – Spices like cinnamon, cloves, and star anise are simmered with red wine to create this comforting holiday drink.

Spiced hot chocolate – A festive twist on a classic, often enhanced with cinnamon or nutmeg.

Turkey stuffing – Sage, rosemary, and thyme are the stars of this savoury side dish.

Christmas pudding – A rich dessert spiced with cinnamon, nutmeg, and cloves, often served flaming with brandy.
