All you do is measure out the yeast and mix it with the water called for in the recipe. Yeast is happiest at about 75Â°-80Â°, so the water should feel barely warm or lukewarm to the touch. Add just a pinch of sugar to give the yeast something to munch on. Let the yeast and water sit for a few minutes. First, the water will dissolve the dry coating around the granules of yeast, releasing the active yeast inside. The active yeast will go to work on the sugar and a bubbly foam will start to form on the surface from the carbon dioxide being released. This foam is proof that the yeast is active, and once you see it, you can add the yeast to your bread dough.
A laryngoscope is an illuminating medical instrument used by healthcare providers to allow visualization of the pharynx and larynx of a patient. The pharynx is the area directly behind the nose and mouth, and the larynx is better known as the voice box.
Rigid laryngoscopy: 1  You will lie on your back on an operating room table, and general anesthesia is administered. 2  A rigid laryngoscope is inserted into your mouth and the doctor inspects your throat and larynx. 3  Instruments may be passed through the scope to remove tissue samples for laboratory analysis.
