When organizing the puree, the practical question comes before the recipe: how many cassettes are needed? The yield is not fixed because water, maturation, waste and desired density change. As a conservative estimate, approximately 5-7 liters of puree are obtained from 10 kg of healthy tomatoes, but the value must be checked on your equipment.
Yield calculation
A very watery tomato loses more volume during cooking; a meaty one produces a thick sauce more quickly. Petioles, damaged parts and removed peels affect. For ten 700 ml bottles it is best to plan for around 10-13 kg of tomatoes, leaving a margin.
Make a pilot batch
Work 2 kg first, measure the amount obtained and multiply. It is more precise than any table because it incorporates variety, degree of ripeness and home tomato press.
Why choose the oval tomato
The elongated shape and the pulp suitable for processing make sauce and puree easier. Look for fruit that is ripe but not mushy: damaged tomatoes are no saver when you need to preserve. Separate them during washing and use the only bruised ones for a sauce to be consumed immediately.
Uniform maturation
A cassette can contain different shades. Leave the firmer fruits to ripen separately and work those at the same point together, so cooking and density are more regular.
Organize equipment and times
First prepare suitable bottles, new caps, pots, tomato press, funnel and clean cloths. Divide the work between washing, cutting, cooking and bottling. A large quantity managed without space increases errors and lengthens times.
Safety of preservation
Pure intended for the pantry requires reliable acidification, filling and heat treatment procedures. Follow updated official guidelines for home canning and don’t improvise times based on the color of the cap alone. Alternatively, freeze portions of the cooked and cooled sauce.
When to discard a jar
Swollen cap, leak, foam, abnormal odor or opening without vacuum are signs not to taste. Safety comes before waste.
Order the right quantity
Count bottles, monthly consumption and real space. One cassette is suitable for a small batch; multiple boxes require people and equipment. If it’s your first time, start small and note the initial weight, final liters and time: the following year you will have a calculation based on your kitchen.
Practical questions before buying and cooking
How do I choose quantity and format?
Start from the number of people and how many times you will actually use the ingredient. For a test or a single recipe, a small format is more rational; a larger cassette or package makes sense when you have already planned more preparations. Write a mini plan: fresh consumption, main recipe and possible transformation of leftovers. This calculation avoids both running out of raw materials halfway through the job and avoiding buying more than you can store well.
What do I check when the order arrives?
Open the packaging, check the integrity and immediately separate the more mature or delicate elements to use first. Fruit and vegetables are not identical objects: size, color and scent can vary with season and harvest. Follow product-specific storage directions, keep containers dry and do not close damp foods without ventilation. For jars and packages, check the seal, label and storage methods after opening.
How do I get a balanced result?
Taste before adding sugar, salt, vinegar or spices. The recipe provides a starting point, while the actual product decides the final fix. Proceed in small steps and note the doses and yield: with the next preparation you will also be able to better choose the quantity to order. A recognizable raw material often requires fewer accessory ingredients and leaves the dish with a clearer taste.
