Salsa de Molcajete. Salsa de Molcajete refers to a salsa that is ground by hand in a molcajete, Mexico's version of the mortar and pestle. Nearly all salsas used to be prepared this way, but now many cooks use blenders and food processors. Because of this, even in Mexico the term evokes nostalgia for the handmade quality of bygone days.

The respiratory tract refers to the pathway that carries air to the lungs, and can be divided into upper and lower parts. The lower respiratory tract consists of the lungs and windpipe, while the upper respiratory tract includes the nose, sinuses, throat (pharynx) and voice box (larynx). Although sinusitis, laryngitis and strep throat are all infections of the upper respiratory tract, the term URI usually refers to acute viral rhinitis. Another name for this condition is the âcommon cold.â. The symptoms of a viral URI typically include nasal congestion, sneezing, and a runny nose with clear mucus.
