Ratios: With berries ratios are a little harder to establish because one strawberry might be very small, but be almost entirely flavorful red flesh, while another strawberry might be huge, but most of the mass might be white pith which provides nothing to the flavor. So as a general rule, I start by removing the green top of my freshly rinsed strawberries. Then I fill a jar with them and pack them down lightly, but not enough to bruise the fruit. Then I barely cover the fruit with my alcohol. This insures maximum flavor, and with fruit you can't really over brew the flavor. You can leave strawberries in the liquor almost indefinitely with no adverse effects to the finished product.
Flavor Profile: This infusion tastes like strawberry. Pretty much all of the base flavor is imbued into the alcohol. It is slightly tart, very bright and exceptionally light. It goes very well with fizzy things, and all other fruits. It does not pair well with turbinado syrup, or other sweeteners that have their own distinct taste. I generally pair strawberry with simple white syrup.
