The type of material depends on your preference or need. Turkey basters, nowadays, are either made of stainless steel, high resistant glass, silicone or plastic. If you are the type that prefers a transparent tool that allows you to easily see the contents of the baster, then choose the glass type.
If you are the type who prefers a durable tool that does not easily break, then pick the ones that are made of food-grade stainless steel. If you are the health conscious type and would not risk your family ingesting harmful chemicals, then do not buy a baster that is made of plastic. If you want a lightweight kitchen tool that is easy to clean and does not easily break, choose the ones made of silicone. The downside of silicone is that it tends to retain the smell of the marinade and other basting liquid. Many consumers prefer basters made of stainless steel because they last for a long time. This material can withstand extreme heat and does not warp or deform through regular use. It is also very easy to clean as it does not retain the smell of the marinade or basting liquid. Most importantly, it does not corrode, rust, or resist to high temperature and release harmful chemicals.
