Tour the route for the meal they will make
Ask the visiting cook about the first few steps of their recipe. For pancakes, show the mixing bowl, measuring tools, pan, and spatula in the order they will use them. Explain where to put used dishes and which work surface is available. That short route is easier to remember than a tour of every cabinet.
Protect ingredients reserved for another dinner
Tell them which items are reserved for another meal and where used dishes belong. If they use unfamiliar equipment, let them ask the owner or consult its instructions. A small note beside the planned meal helps more than expecting them to infer the household's routines.
Show the visitor which food is available and which has a named purpose. “These eggs are for breakfast; the carton on the lower shelf is for your batter” is clearer than expecting them to recognize a household convention. Give them permission to ask if an ingredient or pan looks similar.
Leave equipment questions with the right person
If a control or appliance is unfamiliar, show the manufacturer's instructions or have the owner demonstrate its normal use. The visitor can choose a familiar alternative if necessary. Before leaving the kitchen, agree on serving time, access to any shared equipment, and what the cook would like someone else to prepare.
