Method
- Combine sugar, water, and cream of tartar in a saucepan. Bring to a boil without stirring. Cook until deep amber. Remove from heat and carefully whisk in heavy cream until smooth. Set aside.
- Heat 1 cup caramel sauce with 1 1/4 cups milk to just boiling. Whisk 1 cup milk with egg yolks, flour, and cornstarch. Strain through sieve. Temper hot liquid into yolks slowly. Return to heat and cook until thick. Chill or hold warm.
- Cream butter and powdered sugar until fluffy. Mix in corn syrup and flour. Spread into thin strips (7"x3") on silicone mat. Bake at 300°F for 10 minutes until golden. Immediately shape around greased mold into box form. Cool completely.
- Melt butter in a skillet. Add banana halves, sugar, and cinnamon. Cook 1-2 minutes until lightly caramelized. Remove from heat.
- Toss warm bananas into pastry cream. Fill tuile boxes with mixture. Top with whipped cream and drizzle remaining caramel sauce. Serve immediately.
Notes
Work in stages: Make caramel sauce first (stores for days). Bake tuile boxes next. Prepare pastry cream. Caramelize bananas right before serving.
Tuile timing: You have ~30 seconds after removing from the oven to shape each strip. Work in batches of 2-3. Return hardened tuile to the oven for 15-20 seconds to re-soften.
Caramel safety: Hot caramel causes severe burns. Stand back when adding cream. Use a long-handled whisk.
Serve immediately: Pastry cream softens the tuile within minutes. Assemble at the moment of serving for the best texture contrast.
