Sugar dissolved in an equal volume of water, cooked briefly or shaken cold. The standard sweetener behind a bar, because it blends into cold liquid instantly.
What it does in a recipe: Pre-dissolved sweetness that mixes evenly into cold drinks and brushes onto cake layers without grain. Pick the swap that covers that job — the ratios below are written so you can act on them without doing any arithmetic.
Standard simple syrup is equal parts sugar and water by volume, so splitting the spoonful in half rebuilds it exactly.
MethodStir until you cannot feel any grit on the bottom of the glass. Warm water dissolves it in seconds; in a cold drink, undissolved sugar will simply settle out.
Trade-offIdentical once fully dissolved. The only failure mode is not stirring long enough.
Simple syrup keeps about a month refrigerated; rich 2:1 syrup keeps longer because the higher sugar concentration inhibits spoilage. Cloudiness or any smell of ferment means it should be thrown out.
Cooking around an allergy? Diet tags here describe the ingredient itself, not any particular brand. Processed products change formulation without notice and shared production lines are common, so read the label on everything you use. A severe allergy is a medical matter — confirm with the manufacturer or your clinician rather than relying on a substitution chart.
