New Star 1029017 Non-Slip Silicone Pastry Mat, Extra Large with Measurements, 16x26'', NSF Certified

Great product! Fits perfectly in my 14 7/16”x 20 7/16” cookie sheet. Easy to clean. Big difference in heat distribution when using this product. Used the same cookie sheet, same temp & cook time, the edges of the cookie that was NOT on the silicone mat (left) were very brown while the cookie baked on the mat (right) was cooked evenly. Both were baked the same in the center.

I use these in my professional kitchen and so far they’ve held their own and do the job! Great product.

No more parchment paper for me!

I have now used this mat for baking granola and cooking caramelized sweet potatoes. It’s “grippiness” takes a little getting used to, but once one gets beyond that, it’s a great tool in the kitchen. I was worried veggies wouldn’t properly caramelize on it, but that was no problem. Removal from the mat is super easy, and I imagine it lends some heat distribution qualities as well when using a cheap pan. It also keeps the food off the aluminum, which is a big benefit to me.Other reviewers have complained about cleaning the mat. I have found the best way to clean the mat is right inside the pan. It’s super easy to scrub and rinse when supported by the rigid pan. The pan doesn’t need to be scrubbed, so it can just air dry after. I throw the mat over a shower rod or the oven handle to dry. I’d like to get a few more in multiple sizes.

I live an apartment and have a small oven. I bought smaller cookie sheets but I was afraid that I wouldn't be able to find smaller silicone mats. I found these and I am so happy. They fit in the quarter sized sheets perfectly. My only gripe is that these can get a little hard to clean but it's better than cleaning up my pans.

My 5 star rating isn't for it's baking non stick abilities! Why, first because silicone, beyond hardly anything sticking to it and so overlooked is that silicon is an insulator, not a conductor. Silicone has many other applications, also is a liquid in aviation for dampers and as brake fluid that I used many years ago in my automobiles and motorcycles brake systems. When antilock brakes took over brake systems in automobiles, had to stop using it. Silicon does not absorb moisture.Anyone have silicon covers for their cast iron fry pan handles to protect hands from serious burns. I noticed when using them to remove something really hot from the oven, they got a little sticky.This brief explanation MAY help for mats said to burn when the oven temp is set to 400. At 400F, that can be getting close to silicon break down temperature, it starts to get sticky.For what it's worth department, I don't use anything but metal or clay bakers for high temperature baking. I bake my bread at 450F in a 2 quart clay baker, no parchment paper necessary. I start out in a cold oven to not stress the clay baker. My bread recipe, 450 grams of flour with 300 grams of water (plus other ingredients) takes 35 minutes to bake with it's pre-soaked in water clay baker lid installed.So, the oven has to get briefly hotter then the set temperature because the oven thermostat regulates the temperature by turning the elements on and off to maintain that set temperature. How often it cycles, or how big the spread between the high and low temperature when the elements are on and off matters. Watch the element sometime, it gets red when powered and then dark when cycled to off.Your home heating/AC thermostat operates in a similar way, cycling off and on to maintain the set temperature.Below some info from "Moms Baking Company" I quoted from them. Then why I bought my mat, after the long winded dialogue, not for baking."Baking in/with silicone takes longer than baking in metal. Why? Silicone, like glass, is an insulator rather than a conductor. This means baking occurs slower in silicone molds, hence baking time and even temperature may need to be altered.As most recipes will assume you’re using metal bakeware, you may need to adjust your temperature and bake time when using silicone molds. When using silicone, you may wish to reduce the temperature by 25ºF (10ºC) and/or cook for 5 to 10 minutes longer – thicker batters will need longer than thinner batters or lighter cakes like sponge cake. This makes silicone ideal for lighter baking such as light cakes, muffins or quick bread."I use this mat on half of our smooth top electric stove to keep from damaging the glass top when objects are constantly placed on it. I would consider using a silicone mat for kneading my bread dough instead of an oil sprayed cut board.

After initially searching for silicone mats for our cheap tiny baking sheets, I decided that I wanted to buy new sheets, mats, and cooling/cooking racks. I searched and searched and read so many reviews of Sheets that warp, lose their form, collect water, rust, Mats that smoke and/or emit strange odors - what? and Racks that have poor welds, rust, warp, or are just weak and can't support much weight. I began to lose confidence in the ability to find something reliable here on Amazon. I adjusted my search criteria multiple times before this brand, New Star Foodservice, showed up. As I read the reviews my confidence slowly returned and I decided to proceed with my purchase. I paired these with heavy duty stainless steel racks from Hamilton Housewares. I puchased (2) 1/4 sheet sets for our toaster oven, (1) 1/2 sheet set and (1) 2/3 sheet set which is the largest that will fit in our conventional oven.My wife and I are stoked! We now have these high quality sheets each with a silicone mat and cooking/cooling rack in all these sizes. So far so good! Everything cleans up so easily and we do not see any of the multitude of issues reported by other reviewers.

Excellent product. Fast delivery too. I recommend!
