Use a food processor to knead the dough; it's the easiest way to make unleavened dough in my opinion! Put the dry ingredients (all-purpose flour, corn flour, salt and baking powder) in the bowl of the food processor and process for a few seconds to mix well!: As the blade whirls you will hear a soft chopping sound and sense the dry mixture first becoming sandy, then slightly clumped, which is the key cue that the flour and corn flour are ready to receive fat. The food processor speeds the job while keeping the butter cold, which preserves pockets of fat for flakiness. Why it matters, the rapid pulsing limits heat transfer from your hands so the butter does not melt prematurely, resulting in a tender, layered crust. If the dough warms too much you'll lose that flakiness, so pause if you notice a tacky, greasy texture and chill the bowl briefly.
Then add the diced cold butter, beaten egg, and cream cheese, then process all the ingredients at maximum speed until a compact ball of dough forms!: Right after pulsing, you should smell the faint toasted scent of the combined flour and note the uniform pale color, which tells you the salt and baking powder are evenly distributed. This step ensures even rising and consistent seasoning throughout the crust. A common mistake is skimping on this blend, which leads to pockets of unbalanced flavor; take the extra few pulses to avoid that.
Wrap the dough in plastic wrap and refrigerate for half an hour, or, if you're in a hurry, a quarter hour in the freezer!: You will see the mixture suddenly come together into a cohesive mass that clings to the blade, signaling the right moment to stop. The butter should still show tiny flecks if you inspect closely, which will create steam channels in the oven and give a layered bite. The dough will feel cool to the touch and slightly tacky, not wet. If it seems too dry, add a teaspoon of cold water at a time; if it gets too wet, chill it to firm it up.
Place the cold dough on a floured board and roll it out into a 0.5-0.7 cm (~1/4 inch) thick sheet and cut out circles slightly larger than the pans you are using to bake the mini-tarts.: Cooling the dough firms the butter and relaxes the gluten, which helps the pastry remain tender when rolled. I love the quiet patience of this pause, which lets flavors settle and textures stabilize. Avoid skipping this, because warm dough will shrink and lose its shape while baking, making the tart shells distorted instead of neat.
Lightly butter the tart pans and line them with the circles of dough, pressing the dough against the side of the pans with your fingers, then prick the dough in places with a fork.: As you roll, you will see the dough smooth and even out, with the surface taking on a matte sheen that indicates proper hydration. The thickness ensures the shell bakes crisp but still fragile enough to bite through. If you press too hard while rolling you will compact the layers, causing a tough crust; let the roller glide with light pressure and reset the dough in the fridge if it becomes too warm.
Put the mini tarts in the fridge for 10 minutes, while the oven heats up to 190°C/375° F.: When you press the dough into the pan you should feel it snugly conform, with tiny air pockets trapped under the surface that will expand slightly in the oven. Docking the bases with a fork prevents blistering and keeps the bottoms flat for a neat filling. One misstep is overworking the dough while pressing, which can make the crust dense; press gently and avoid stretching the pastry.
Bake the dough for 10 minutes, then remove it from the oven. Fill the tartlets with slices of Gorgonzola cheese, and top with slices of pear.: Chilling again before baking helps the crust hold its shape and encourages an even rise. You will feel the pan cool to the touch and see the pastry firm up, which makes it easier to transfer to the oven without distortion. If you bake from warm pastry the edges may slump, so resist the urge to rush this short rest.
Brush the pear slices with some melted butter. Finally, sprinkle over a few chili flakes and some red pepper, then return the tartlets to the oven for another 10 minutes or until the shells are golden brown and the gorgonzola cheese is bubbling.: In the oven you will witness the color shift from pale to light golden, and the kitchen will take on a toasty, buttery aroma. Pull them at the ten minute mark when the edges are just taking color but the base is set, then layer on the creamy gorgonzola and the sliced pear . The layering matters because the cheese will melt and mingle with the fruit, creating pockets of creamy, sweet tang. A common miscue is overbaking the shells first, which can make the final tart dry once the filling finishes cooking.
Serve hot or cold decorated with small sprigs of rosemary!: Brushing pear with melted butter gives them a glossy finish and helps them caramelize slightly in the oven, contributing to aroma and texture. As they bake you will hear a quiet bubbling as the gorgonzola softens and sputters at the edges, while the tart shell deepens to a warm brown. The chili flakes ignite gentle heat that lingers after the first sweet bite. Avoid leaving them in too long, because the cheese can separate and become greasy rather than luxuriously creamy.
Serve hot or cold decorated with small sprigs of rosemary: The final presentation is a visual and aromatic flourish. When served hot, the cheese is melted and creamy and the crust sings with warmth; when served at room temperature the flavors have time to settle, producing a balanced profile. Tuck a small rosemary sprig into each tartlet for fragrance and a rustic look. A common oversight is forgetting to cool slightly before transporting, which can cause the filling to slump in transit, so allow a short rest if you need to move them far.
