A generous spoonful of one paprika may add color and gentle sweetness. The same quantity of another can make the whole pan hot or intensely smoky.
Check the description before using an unfamiliar jar. If a recipe asks for smoked paprika and yours is hot, begin with less and adjust after tasting. Add paprika to warm oil briefly, then bring in a moist ingredient before the spice scorches.
Smokiness is especially noticeable in simple beans or potatoes. Use enough to give direction without making every ingredient taste like the same seasoning. Store the jar tightly closed away from heat and light. If the aroma has become faint, replacing a small tired jar is usually more satisfying than trying to compensate with several large spoonfuls.
