·1 hr 1 min·4 clips

Broccoli can still be used when it starts going yellow, before the furry white bits appear.

1. On the House #56 focuses on sustainable cooking, health, thrift, and environment with Dr. Duane Mellor. 2. Gabriella Jastra hosts Duane Mellor, a UK registered dietitian, science communicator, and medical-school teacher whose work links food to public engagement. 3. The episode asks how household cooking can save money, reduce waste, and still produce meals people want to eat. 4. Mellor describes more than 20 years as a dietitian, including clinical work with people living with diabetes in the UK. 5. He recalls a teaching kitchen at St. Helier in London, where a home economist helped with cooking demonstrations. 6. He also mentions research on chocolate, saying the health benefits are tiny and “not really clinically important.” 7. The conversation turns to household management as using ingredients across multiple meals instead of planning every dish in advance. 8. Mellor names sprouting broccoli, bell peppers, onions, garlic, carrots, celery, lentils, canned beans, and chopped tomatoes as flexible staples. 9. He says chopped tomatoes can become chili, curry, or bolognese-style sauce with different spices from the store cupboard. 10. He defines sustainable cooking partly as “lazy cooking” that uses fewer pans, less washing up, and less energy. 11. He says a microwave usually uses about 700 to 1,000 watts, while an oven uses roughly twice that amount. 12. He explains that slow cookers and pressure cookers work well because they use lower temperatures or shorter cooking times. 13. He compares a slow-cooked chuck steak with a quick steak and says the cooking method changes the energy cost. 14. He recommends batch cooking, freezing portions, and thawing them in the fridge instead of using heat. 15. He says cans of beans, lentils, and a small set of spices can stretch meals while keeping them nutritious and affordable. 16. He argues that meat should often play a supporting role rather than being the “rock star lead singer” of the plate. 17. The tone is practical and conversational, with Gabriella Jastra asking examples and Duane answering in plain, kitchen-level language. 18. The format mixes biography, definitions, and repeated back-and-forth examples rather than a formal lecture. 19. People interested in frugal home cooking and food waste. 20. Listeners wanting celebrity culture or recipe-only content. 21. The best audience is anyone trying to cook cheaper meals without wasting ingredients. 22. The episode is not aimed at listeners looking for strict meal plans or gourmet technique. 23. Mellor’s host credentials are not stated in the transcript, beyond Gabriella Jastra introducing herself as the host.
