Lassi Calculator for Any Number of Glasses

How the lassi calculator works

The lassi calculator multiplies every ingredient in your one-glass recipe by the number of glasses you want. You enter what goes into a single glass, the way you already make it, and it shows the amount of each ingredient for the whole jug:

amount for the jug = amount for one glass × number of glasses

It then adds up two totals. Every row measured in millilitres, litres, cups, fluid ounces, pints, quarts or gallons counts as liquid. Every row in milligrams, grams, kilograms, ounces or pounds counts towards a separate weight total. Spoons and items such as ice cubes are in neither total. If you enter your jar size, it checks the liquid against it and, if it is too much, how to split the blending:

glasses per round = usable jar fill ÷ liquid in one glass, rounded down

rounds = number of glasses ÷ glasses per round, rounded up

Spoon, cup and item amounts are shown as kitchen fractions, the same way as in our recipe scaler. Grams and millilitres are shown as decimals. Any amount that had to be rounded is marked, with its precise value next to it. A metric teaspoon is 5 mL and a metric tablespoon is 15 mL.

Worked example: mango lassi for twelve

The example recipe is a simple mango lassi for one glass. It is only an example; every family makes it differently. Here it is scaled to 12 glasses:

Ingredient	One glass	12 glasses
Plain yogurt	100 g	1,200 g (1.2 kg)
Milk	100 mL	1,200 mL (1.2 L)
Mango pulp	80 g	960 g
Sugar	1 tsp	12 tsp (60 mL)
Ice cubes	3 items	36 items

The only liquid row is the milk, so 12 glasses need 1,200 mL of liquid. The weighed rows add up to 180 g per glass, 2,160 g in all. With a usable fill of 1,000 mL, that is 200 mL too much. Up to 10 glasses fit in one round, so the calculator suggests 2 rounds of 6 glasses each. Remember that the yogurt and mango take up room in the jar too, so choose a usable fill that allows for them.

Why are yogurt and fruit counted by weight?

Yogurt and mango pulp are usually measured on a kitchen scale, and a weight cannot be turned into a volume without knowing the density. Thick curd, thin dahi and fresh pulp all differ, so the calculator never guesses. It keeps grams as grams and shows their total beside the liquid total.

To judge whether everything fits, blend one glass of your own recipe once and note how full the jar looks. Or measure the yogurt in a cup instead of on the scale, and it will count as liquid in the jar check.

How do I measure my own glass?

Make one glass the way you like it and measure as you go. Weigh the yogurt and fruit, pour the milk or water from a measuring jug, level off spoons of sugar and count the ice cubes. Then enter each ingredient on its own row in the lassi calculator.

• Sweet lassi. Yogurt, a little water or milk, and sugar. Add rose water or cardamom as spoons or items if you use them.
• Salted lassi. Yogurt, water, salt and roasted cumin. Enter small amounts as a fraction of a teaspoon, such as 0.25.
• Mango lassi. Yogurt, milk, mango pulp and sugar, as in the example. For the method, see our mango lassi recipe.
• Other units. To change ounces or US cups first, use the kitchen unit converter.

Tips for making lassi for a crowd

• Leave headroom in the jar. Blending whips air in and the lassi foams up. A jar filled to the brim can spill, so a jar that only just fits the liquid may still be too small.
• Blend in rounds. When the jar is too small, blend one round after another into a large jug and stir well. Enter the glasses for one round in the lassi calculator to see its amounts.
• Sweeten at the end if unsure. Guests may like it less sweet. Taste first, then stir in the sugar.
• Add ice late. Ice melts and thins the lassi, so add it to the glasses or in the last seconds of blending.
• Cost it. To see what a jug of lassi costs, enter the batch amounts in the recipe cost calculator.

What this calculator does not do

The lassi calculator only does arithmetic on the recipe you enter. It does not know how thick you like your lassi, it does not convert weight to volume, and it does not melt your ice. It also gives no nutrition or health advice. To read about the fruit itself, see our guide to mango health benefits.

Sources used on this page

This page cites no outside sources. Everything on it is plain arithmetic on your own recipe, and the metric spoon sizes (5 mL and 15 mL) are the definitions used by the tool itself, so the lassi calculator works the same for sweet, salted or mango lassi.
