1. Kentucky Hot Browns
For party-purposes, maybe make them in miniature.
2. Mint Juleps
(More importantly, pewter julep cups.)
Serving mint juleps in highball glasses is fine (heck, even a Solo cup can't ruin something with so much bourbon), but really you should use your Derby party as an excuse to buy perfect, adorable julep cups (great selections here, but you can find them in any kitchen store).
If a classic mint julep is a little too potent for you, try adding fruit or juice.
3. Mint Julep-Themed Desserts
If want to have your roses and eat cake, too, try your hand at a rose cake.
Rose cookies are a little bit easier, but equally lovely.
5. Bourbon Balls
6. Really, bourbon everything.
7. Benedictine Spread
Making benedictine sandwiches is even more adorable.
If your food is cute enough, it counts as a decoration.
9. Pimento Cheese
Pro-tip: pimento cheese is a great add-in for next-level deviled eggs.
It also makes for especially awesome jalapeño poppers.
10. (Unofficial) Derby Pie
11. Really Amazing Hats
Any brimmed hat can be a Derby-ready one when adorned with some ribbon and a silk flower.
