Make the Buttermilk:
- Combine milk and lime juice (or vinegar) in a bowl. Let sit for 15 minutes to curdle.
Make the Cake:
- Preheat oven to 350°F (175°C). Grease and flour a bundt pan.
- In a large bowl, cream margarine and sugar until light and fluffy.
- Mix in the orange and lime zest.
- Add eggs one at a time, beating well after each addition.
- In a separate bowl, whisk together flour, baking powder, and baking soda.
- Add dry ingredients to the wet mixture, alternating with buttermilk. Mix until smooth.
- Pour batter into the prepared bundt pan.
- Bake for 1 hour, or until a toothpick inserted into the center comes out clean.
Make the Glaze:
- Strain orange and lime juice into a saucepan. Add sugar and rum.
- Bring to a boil over medium-high heat.
- Reduce heat to medium and stir until sugar is dissolved. Remove from heat.
Finish:
- While cake is still warm, pour glaze evenly over the top.
- Let the cake cool completely before turning it out onto a wire rack.
