Sugar Substitution Calculator — Honey, Stevia, Cane Sugar, Erythritol

The standard conversion is: use 0.75g honey for every 1g white sugar (or 75% by weight). Because honey contains 17–20% water, you must also reduce the total liquid in the recipe by about 20ml per 100g honey used. Honey is sweeter than sugar per gram and browns more quickly, so lower the oven temperature by 10–15°C and watch the colour carefully. In Italian pasticceria, honey works well in soft biscotti, torta di miele and certain cakes, but less so in delicate sponges where the moisture can collapse the structure.

Stevia is approximately 200–300 times sweeter than sucrose, so the typical ratio is 1g stevia powder for every 200–300g sugar. However, most commercial stevia products are pre-diluted blends: check the packaging, as common Italian products like Truvia or Stevia Natreen require a 1:10 ratio (1g product per 10g sugar). Pure stevia extract is much more concentrated. Note that stevia provides no bulk, so substituting large amounts of sugar with stevia may require adding erythritol or another bulking agent to maintain texture.

Erythritol is approximately 70–80% as sweet as sugar, so you need 1.25–1.3g erythritol per 1g white sugar for equivalent sweetness. Unlike sugar, erythritol does not caramelise or brown, which affects the final colour of biscotti and cakes. It also has a noticeable cooling sensation when consumed cold. For hot baked goods, erythritol performs reasonably well structurally, but Italian pastry professionals often blend it 50/50 with xylitol or inulin to reduce the cooling effect and improve texture.

Agave syrup (sciroppo d'agave) is 1.3–1.5 times sweeter than sugar, so use about 0.67–0.75g agave per 1g sugar. Like honey, it adds moisture: reduce other liquids by 15–20ml per 100g agave used. Agave has a very neutral flavour, making it one of the cleanest liquid sweetener substitutes. It works well in crostate fillings and soft doughs, but can make biscotti and crackers softer than desired due to the added moisture.

Raw cane sugar (zucchero integrale di canna) is a 1:1 weight substitution for white sugar — no adjustment needed. It contains 3–5% molasses, which adds a subtle caramel flavour and makes baked goods slightly moister and darker. Italian pasticcieri often prefer it for torte rustiche (rustic cakes), cantucci and castagnaccio. For very delicate preparations like crema pasticcera or génoise sponge, stick with white sugar for a cleaner result.

Yes, significantly. White sugar plays several structural roles: it tenderises gluten, holds moisture (hygroscopic), provides bulk, aerates fat when creamed, and assists leavening in acidic batters. Liquid substitutes (honey, agave, sciroppo d'acero) add moisture which can make the batter heavier and prevent proper rise. Non-sugar sweeteners lack browning reactions (Maillard and caramelisation). For best results in Italian torte, replace no more than 50% of the sugar with an alternative and test the result before using it in professional production.
