The best material for teaspoons is stainless steel. Stainless steel teaspoons are durable, easy to clean, and resistant to corrosion, making them a practical choice for everyday use. According to a study published in the Journal of Food Science, stainless steel teaspoons are less likely to leach harmful chemicals into food compared to other materials like plastic or ceramic. This is because stainless steel is a stable metal that does not react with food or beverages, ensuring that the taste and quality of the tea are not compromised. Additionally, stainless steel teaspoons are more resistant to wear and tear, which means they will last longer than teaspoons made from other materials.
