Percentages of total energy (calories)
A charming harmony between the refreshing tang of lemon and the sweetness of an airy meringue that is crisp outside and soft inside: the tart sits on a crumbly shortcrust base, topped with rich lemon curd and crowned with egg white whipped with sugar. It stands out for the natural acidity of lemon; some studies suggest acidic foods may help slow stomach emptying, which may explain why its glycemic index is lower than that of many similar desserts.
💡 Smart Nutritional Guidance
Consumption advice
Meringue is egg white and concentrated sugar; enjoy the lemon curd with the base and take only a very small part of the meringue top to noticeably cut the sugar in your portion.
Best preparation methods
Using almond flour for the tart base adds healthy fats and good plant protein and greatly reduces the carbohydrate in the base.
Important Nutritional Note
Although the glycemic index (55) is low, the glycemic load of a full slice is high (24.7), so portion size is what decides whether blood sugar rises.

Frequently asked questions
Does lemon juice really lower the glycemic index?
Some studies suggest that adding acidic foods (such as lemon juice or vinegar) to a starchy meal may slow stomach emptying and soften the rise in blood sugar afterwards, but the effect is modest and does not cancel out the sugar in the meringue.
Does lemon meringue tart suit a low-calorie diet?
Its fat content (11 g per 100 g) is lower than that of chocolate and buttercream desserts, but it is still rich in simple sugars that call for moderation.
How do I calculate the available carbohydrate in lemon meringue tart?
Subtract the fibre (1.3 g) from the total carbohydrate (46.2 g) in a typical slice, giving about 44.9 g of available carbohydrate.
