What would you do? Scenario: You, and SI are in attendance of a "cooking class" exhibition which includes enjoying the multi-course dinner that was prepared in demonstration. Chef/Presenter states what you know to be a obvious, and elementary blunder about a cooking technique that would dramatically affect the outcome of the dish. Do you say something, or bite your tongue? Did not know the level of culinary ability of the other attendees, but no one else blinked in eyelash at the blooper. TIA.
