You could try the jam jar method so there is no check by transplanting.
Put a large jar upside down over the final growing place to warm the soil for a day. Sow seed on it's edge in a pocket of compost and replace the jar to act as a cloche until germinated and grown into a small plant.
It is worth a punt even if you only get a few fruits at the end of the season. Depends how far north you are though.
