I was reading about https:&#x2F;&#x2F;en.wikipedia.org&#x2F;wiki&#x2F;Mille-feuille and then googled when the thermometer was invented, https:&#x2F;&#x2F;en.wikipedia.org&#x2F;wiki&#x2F;Thermometer , then I googled &#x27;how did people bake before thermometers&#x27; among other things and couldn&#x27;t find a satisfactory historical reason. Anyone have the knowledge?
