How many potatoes do we need to make 1kg of frozen chips?

It's impossible to give you an exact number of potatoes needed for 1kg of frozen chips without knowing a few more details. Here's why:

* Potato Variety: Different potato varieties have different water content and density. Some potatoes are naturally larger or smaller, and some have more starch than others, affecting how much they shrink during processing.

* Chip Type: Thin-cut chips will require more potatoes than thicker-cut chips for the same weight.

* Waste: There will always be some waste during peeling and cutting potatoes.

General Estimate:

* As a rough guideline, you can expect to need around 1.5kg-2kg of raw potatoes to make 1kg of frozen chips.

To get a more accurate estimate, you could:

1. Check the packaging of frozen chips: Some brands may list the potato weight used in their recipe.

2. Experiment: Try making a small batch of chips using a known weight of potatoes and see how much you end up with.
