Cake

1. Preheat the oven to 350°F; grease an 8-inch springform pan and line the bottom with parchment paper, and wrap the outer bottom with aluminum foil, then set on a rimmed baking sheet. 
2. In a bowl, whisk the flour, cinnamon, baking powder, baking soda, cloves, allspice, salt, and ginger. 
3. In another bowl, whisk together the oil and honey. 
4. In a stand mixer fitted with the whisk, beat the eggs with both sugars at medium-high speed until thick and nearly doubled in volume, about 4 minutes. 
5. Gradually beat in the oil-honey mixture until just combined, about 1 minute. 
6. In a small bowl, combine the tea, juice, and paste. 
7. At low speed, in three alternating additions, add the dry ingredients and the tea mixture, until just combined. 
8. Scrape the batter into the prepared pan. 
9. Bake for 55 minutes, until a toothpick inserted in the center comes out clean. 
10. Transfer the cake to a rack, and let cook for 1 hour. 
11. Run a knife around the edge of the cake, and remove the springform ring. 
12. Invert the cake, and remove the springform bottom; discard the parchment paper. 
13. Let the cake cool completely, about 45 minutes, then transfer to a cake plate. 

Frosting

1. In a small saucepan, whisk ½-cup sugar with the flour, then whisk in the milk. 
2. Bring to a boil over moderately low heat, whisking constantly, about 10 minutes. 
3. Scrape into a heatproof bowl, and press a sheet of plastic wrap directly onto the surface; let cool 1 hour. 
4. In a stand mixer fitted with the paddle, beat the butter with ½-cup sugar and orange zest at medium speed until fluffy and smooth, about 5 minutes. 
5. Beat in the cool milk-flour mixture, 1 tablespoon at a time, beat well after each addition. 
6. Beat in the vanilla and salt, and continue beating until smooth, about 2 minutes. 
7. Spread a thin layer of frosting al over the cake, and refrigerate until set, about 15 minutes. 
8. Spread the remaining frosting all over the top and sides of the cake. 
9. Refrigerate until the frosting is just firm, about 30 minutes.

1. Bring the water and sugar to a boil. 
2. Add the orange slices, and simmer for 30 minutes. 
3. Transfer the slices to a rack to cool. 
4. Top the cake with the slices before serving.
