Check as you go along - sometimes just a little extra salt & pepper
Follow recipes carefully to start and learn what you notice - I rarely sear meat unless cooking for guests as I really don’t mind the difference. I always add more garlic . often add a teaspoon sugar into tinned tomatoes. Cheese in anything
Patterns can help
like something with texture to balance something smooth like a crispy roast potatoe with a turnip and carrot mash - cheese and crackers then adding grapes give another texture
something hot with something cold - hot crumble cold ice cream , side salad is cool and crisp with a hot creamy lasagne
something sweet with something sour with something spicy with something cooling with something salty - salt, sugar, oil, vinegar , spices - where will each element come from ? Salt can be salt or soy or cheese for example, sugar can be honey, or natural in the veg edit to add or fruit in a curry or Middle Eastern dish - acidity from vinegar or lemon juice
and learn your favourite spice combos - a grating of nutmeg and cayenne , a handful of dried oregano , garlic in anything , smoked paprika … find your go to to jazz up an element of a meal
