Divide the strawberries into 4 ramekins and fill the ramekins to the top. (The strawberries will bake down so if the ramekins are overflowing that is fine.) Sprinkle 1/4 cup of white sugar over the tops of the strawberries. In a medium bowl combine the flour, oats, butter, brown sugar, remaining white sugar and salt. Using a hand-held mixer, blend the ingredients until they are just incorporated and have a crumbly consistency. Sprinkle the mixture over the tops of the strawberries. Place the ramekins on a baking sheet and place into pre-heated oven and bake for 30 minutes, until the top of the crisps turns golden brown. Remove from oven and let cool slightly before eating.
