Crumble de Membrillo y Kiwi

So, it was Señor Spoon's Cumpleaños the other day, I gave him the option of cake or cumble (and custard) - I think you can decipher what he chose...

So, the recipe is appropriated and slightly amended from the Good Food website: goodfood.uktv.co.uk/recipe/quince-crumble/

7 quince, 7 kiwi, bad lighting.

The stuff:

• 7 membrillos/quince
• 7 kiwis
• 6 clavos/cloves
• 2 tsp canela molido/ground cinnamon (1 tsp in each: quince mix and topping)
• 200g azucar/sugar  (100g in each: quince mix and topping)
• 300 g harina de trigo/plain flour
• 100 g mantequilla/butter

The how:

1. Right, this bit takes for-ages, so, rope-in a willing, or not, volunteer, even it is his birthday. Peel, core and chop the quince into chunks, chuck into a pan of water as you go, 'cos they'll start to turn brown in the time it takes to do them all! "It's worth all the prep" Señor Spoon states!
2. Drain off water some water to leave just enough to cover the quince pieces, add cloves and just 1 tsp cinnamon.
3. Give the pan a hat and bring it to the boil, add in 100g of sugar, you'll need the rest for the topping - cover and simmer for 5 minutes.
4. Simmer quince mix, without a hat, until the quince is cooked - around 15-20 minutes (the original recipe asked to simmer until the liquid is syrupy, but mine didn't get that far before the quince were soft).
5. While patiently waiting, peel and chop up the kiwis and plonk in your allocated crumble dish.
6. Make the crumble topping, ratio I use is 1:1:3, butter:sugar:flour, chuck butter and flour to bowl, using finger tips, rub together until bread-crumb-like, mix in remaining 100g sugar and teaspoon of cinnamon, keep about the place.
7. Back to the now cooked quince, remove lumps with a slotted spoon and add to kiwis, fishing out any cloves you can see, see, see.
8. Stick pan of not-quite syrupy liquid back on the heat to get a bit closer to syrupy liquid, add to other fruit when you're happy with viscosity.
9. Liberally sprinkle crumble topping over fruit. 
10. Stick in the oven, now the one here is, erm, nuclear, so I have no guidelines, other than until golden brown (texture like sun - feel free to listen to the song, it could help, if you don't know what to look out for). I reckon 30 mins in a normal oven will do it!
11. Eat with lashings of custard!
