Lemon Curd Tart (UK Price, Calories & Allergens 2026)
At £3.25 for a 70-gram portion, the Lemon Curd Tart positions itself as a sharp-sweet choice among Costa’s indulgent bakery options. With 337 calories per serving, it leans clearly towards a dessert-like snack, offering a compact but rich treat. This tart is suitable for vegetarians, but anyone with allergies to wheat, egg, milk, or soya should take note before ordering.

The tart’s base pastry, composed mainly of wheat flour and margarine, delivers a classic pastry flavour that balances the zesty curd. This combination underscores its role as a satisfying sweet option rather than something intended as a meal replacement.

Sharp-Sweet Appeal in Tart Form
The Lemon Curd Tart is a small baked dessert that highlights the classic flavour pairing of lemon and butter. The tangy lemon curd filling, made with concentrated lemon juice and lemon oil, creates a bright citrus punch that contrasts well with the sweet and creamy ganache layer. This ganache contains white chocolate and cream, adding richness that tempers the tartness without overwhelming it.
The pastry shell, nearly half of the tart’s weight, brings a traditional bakery note through its wheat flour and vegetable margarine base. The clearly present egg in the lemon curd also adds subtle depth to the flavour profile. Together, these elements form a sharp yet indulgent taste experience that would strongly appeal to those looking for something lively but still comforting.
What the Nutrition Tells Us
With 337 calories packed into a small 70g tart, this is a denser snack than lighter bakery options. The fat content, nearly 19g per portion with over half being saturated fats, confirms a rich, creamy character typical of dessert-oriented pastries. Its 20g sugar content supports the expectation of a sweet treat that satisfies a sugar craving efficiently.
The protein is modest at 3.6g, reflecting the presence of eggs and milk but not positioning this as a filling meal substitute. The low salt level helps to keep the focus on sweetness and citrus sharpness rather than savoury notes. Overall, this tart feels like a satisfying dessert-sized indulgence rather than a meal component or a light snack.
Who Should Choose This Tart?
The Lemon Curd Tart makes sense for anyone seeking a compact, tangy, and sweet treat during a coffee break or as an afternoon dessert. Its vegetarian suitability widens its accessibility, although strict vegan customers will want to look elsewhere due to its dairy and egg content. Allergy-wise, the presence of wheat, egg, milk, and soya means those avoiding these ingredients should not select this option.
Given its indulgent nature and calorie density, it’s likely best suited to those looking for something richer rather than a light nibble. The tart’s sharp lemon notes can appeal to those who prefer dessert options with a citrus edge rather than purely sweet or creamy items.
Allergy and Dietary Considerations
This tart contains several allergens: wheat, egg, milk, and soya. These ingredients notably affect both the pastry and filling components, so customers with sensitivities to any of these should avoid this product. While it is suitable for vegetarians, the combination of dairy and egg excludes those following a vegan diet.
