If you're not sure where to start with this question, you may want to consult a flavor chart! You can find them in your materials from culinary school or online. An interviewer may be asking about flavor combinations to test your creativity and your ability to bake from scratch with or without a recipe. Depending on what you're baking, you only want to combine two or three flavors. You might choose between a fruit, a spice, and a liquor, perhaps even a wildcard like bacon! Let's say your main ingredient is strawberry. You could combine it with mint and rum for a jam or pastry filling. The options are endless. Show off your creativity!
