I made a batch of Toba's glace last night about 9 p.m., and I done some outlining of cookies. When I cleaned up the kitchen, I missed the container with the glaze in it. Naturally it was the first thing I seen this morning. It has milk in it and it went without refrigeration, should I dare use it, or mark it up as a lost and toss it. It was out about 12 hrs.
It's perfectly fine. The high sugar content will keep it from spoiling. I often leave the icing out for days at a time while I am working on the cookies. The decorated cookies are fine left unrefrigerated for a couple weeks, as well. Unless you put in some brite white or white-white food color to the icing, I would not recommend refrigerating the decorated cookies. The cold seems to cause the icing to get cloudy and spotty. (Even Toba does not recommend refrigeration).
Definitely don't refrigerate the cookies. In her book, Toba does say you should store the glace' in the refrigerator -- two weeks with milk three without. I let it come to room temperature to ice and then put back in the fridge when I'm done. Yours should be o.k.
Thanks for the replies. I ended up making another batch, but did not toss away the first batch. I will use it. It makes one think if just the icing has to be refrigerated, how come decorated cookies can sit out for days. It gets confusing, but it will never stop me from making cookies....
What about freezing them? Could you freeze cookies already decorated with the glace?
Mija, you can freeze toba's glace cookies. But be sure to put brite-white (white-white) in your entire batch before you color it, or it will blotch when drying or freezing.
