Onion Jam Tartlets
Add sugar and vinegar and continue cooking on low heat until most of the liquid is absorbed by the onions and mixture is the consistency of jam.
Remove thyme sprig.
Great for hors d'oeuvres or as an accompaniment to hamburgers in place of relish.
Mix together flour and salt. Cut in cold butter until mixture resembles breadcrumbs. Add egg and water mixture a little at a time until dough holds together. Do not knead. Leave dough to rest for at least 30 mins. Roll dough out on a floured surface to about 2 mm thick. Cut out pastry with a round cookie cutter (I used a 4 1/2 cm diameter round cookie cutter) and press into a tartlet tray with holes measuring about 4 cm in diameter. You can of course make it into whatever size you like.
Prick base of pastry with a fork.
Cool before filling.
