1 c. flour
2 T sugar
1 stick ice-cold butter, cut into small pieces
2 T ice water
4-6 med-small pears, peeled and cut into 1 1/2″ chunks
1/2 c. sugar
2 T flour
2 T rosemary needles
juice of 1 lemon
Make the crust: place flour, sugar and salt in a food processor. Add butter and pulse until the butter is the size of small peas. Sprinkle with ice water and continue pulsing until dough comes together in a shaggy mass. Turn out onto a sheet of waxed or parchment paper, bring it together, flatten into a disc and chill for at least an hour.
Preheat oven to 450. Place pears in a large bowl and toss with lemon juice. Place sugar and rosemary in food processor and process until rosemary is finely chopped. Sprinkle pears with about 1/4 c of rosemary sugar and 2 T flour. Toss until evenly coated.
Turn dough out onto floured parchment paper and roll into a rough circle about 8-9″ round. Mound pears in the center, leaving a 2-3″ border, then bring pastry edges up and crimp to seal as needed. Brush the edges with beaten egg & sprinkle top and edges with additional rosemary sugar. Transfer crostada on paper onto a baking sheet and bake for 20-30 minutes until golden brown.
