Introduction to Freezing Aubergine

Freezing aubergine is an effective way to preserve its freshness and extend its shelf life. Whether you’ve grown a bumper crop in your garden or purchased an abundance from the market, freezing ensures that no aubergine goes to waste. While it’s best used in cooked dishes after freezing, frozen aubergine can be a convenient addition to your kitchen.

Can You Freeze Aubergine?

Yes, you can freeze aubergine, but it’s important to prepare it properly. Aubergine has a high water content, which can lead to changes in texture after freezing if not handled correctly. Proper blanching, roasting, or grilling before freezing helps maintain its structure and flavor.

Best Methods to Freeze Aubergine

There are three main methods for preparing aubergine before freezing:

1. Blanching

Blanching is a quick cooking process that helps preserve the texture and color of aubergine.

Best for: Sliced or cubed aubergine that will be used in stews, curries, or casseroles.
How to:
- Boil aubergine slices for 3-4 minutes.
- Immediately transfer to an ice bath to stop the cooking process.

2. Roasting

Roasting brings out the natural sweetness of aubergine and is ideal for dishes like baba ganoush or roasted vegetable medleys.

Best for: Aubergine halves or slices.
How to:
- Roast aubergine in the oven at 400°F (200°C) until tender.
- Cool completely before freezing.

3. Grilling

Grilled aubergine adds a smoky flavor to dishes and freezes well for later use.

Best for: Aubergine slices or rounds.
How to:
- Grill aubergine over medium heat until charred and tender.
- Let cool before freezing.

Step-by-Step Freezing Instructions

Preparation

Choose Fresh Aubergine:
- Select firm, shiny aubergines without blemishes.
Wash and Slice:
- Wash thoroughly and slice into your desired size (rounds, cubes, or halves).
Salt (Optional):
- Lightly salt slices and let them sit for 20 minutes to draw out moisture. Rinse and pat dry.

Freezing Process

Prepare the Aubergine:
- Use one of the methods above: blanching, roasting, or grilling.
Flash Freeze:
