I recently discovered an adoration for cookies & Chai tea (a mix of spices- generally Red Bush, Cinnamon, Ginger, Cardamon, Cloves, Black Pepper, bit of Citrus, etc), so here's the two smushed together. Bit of a hit-and-miss recipe but hope it works for you.
First melt 100g butter and grind up a heaped tablespoon of loose Chai. Throw the Chai in the butter and keep it on a really low heat for about half an hour so the flavour of the tea infuses through the butter. While that's doing, measure out the other ingredients- 100g sugar, 150g flour, 1 egg, a few milk chocolate chips if you want them.
Once the butter's done, sieve out the chai tea bits so you don't have loads floating about in the cookies (a little's fine, it depends how picky your audience is). Then the butter needs to cool for about an hour, which is a bit annoying but necessary. Blog in the meantime.
I found that about half the butter was either absorbed by the tea or bubbled off while it was on the heat, so you might have to top it up with regular butter so you have 100g in total. Cream this together with the sugar, then add in your flour and chocolate. Mix this all together well before adding your egg and stirring it all up, then dollop it out on a baking tray lined with baking paper and bake it for 15-20 minutes. They taste pretty good dunked in milk or just on their own, best while still warm though.
