When it comes to creating homemade spice mixes or meals, you have the freedom to tailor them to your preferences and dietary needs( I mean you have the liberty to control, add or remove any ingredient). Onion peels are a fantastic addition for several reasons: they're packed with beneficial nutrients like vitamin A and C, they contain antioxidants and antifungal properties, and even offer relief from skin itching, and lots more. Plus, their rich flavor enhances the taste of your dishes. So onion peels are not wastes after all. Including onion peels in your curry powder is a nutritious choice that can contribute to your overall well-being. Of course, it's entirely optional, and if you have allergies or preferences, you can always skip them. Thank you so much for tuning in, and I truly appreciate your thoughtful question! 🙏🙏
