The La Caja China Conversion: Inspiration and Materials

This project transforms a standard Weber kettle grill into a La Caja China, also known as a Cajun microwave. The inspiration came from a subscriber's suggestion, sparking the idea to repurpose the kettle for this unique cooking method. The key components include a 23-inch Mexican wok, a 21-inch expanded metal ring (courtesy of Greg from Woodshed Smoke and Barbecue), and heavy-duty aluminum foil.

The Mexican wok serves as the cooking chamber, sitting inverted on the Weber kettle. The expanded metal ring provides a platform for the charcoal, allowing for even heat distribution. Aluminum foil lines the interior of the kettle, creating a heat-reflective surface and facilitating cleanup.

Assembly and Setup: A Step-by-Step Guide

The first step involves lining the inside of the Weber kettle with heavy-duty aluminum foil. The foil should extend slightly beyond the edge of the kettle, helping to seal the cooking chamber and create a drip pan for juices. This creates a clean, efficient cooking environment.

Next, position the inverted Mexican wok inside the kettle. The aluminum foil will cushion the wok and help it maintain its position. The expanded metal ring is placed on top, creating a platform for the charcoal.

Cooking and Temperature Control: Experimentation and Results
