Here are some thoughts, not a recipe as such ... I'm sure others will shoot them down
Start with a fairly lightly hopped kit such as Coopers Pale Ale, which is 25.1 IBU. Add half a kilo of wheat malt extract and, say, 250g of malt extract and 250g or 500g of dextrose (dex is optional and you may want to omit it to keep the alcohol content down). Making it with a kit + 1 kilo of malt will probably result in too much body and it not being too refreshing.
Add 20g Cascade or Galaxy to the hot wort and steep for 15 mins. Dry hop with another 20g or Cascade or Galaxy as fermentation is subsiding. Galaxy is what is used in Mountain Goat Steam Ale.
Well, I guess that is sort of a recipe.
Any comments??
Cheers,
Oliver
