Crushed Malt and Malt Extract

[Bate man]

Hello.

I am attempting to brew the Marstons Pedigree brew from Dave Line's "Brewing beers like those you buy" this weekend and have ordered my ingredients. I found this recipe strange as the only grain I will be using is crushed pale malt and the recipe relies on the use of dextrose and malt extract.

Is the purpose of the Malt extract and dextrose in this recipe to add strength to the beer or am I missing something?

The recipe also asks for Barley Syrup, can this just be substituted with Malt Extract in equal amounts?

Thanks

The recipe in Graham Wheelers book for this beer, uses Pale Malt,Black Malt and some ordinary white sugar.
Hops are a mixture of Goldings and Fuggles.

The extract version replaces the Pale Malt with LME or DME

Too bad that I have already bought my ingredients in readiness so I'll have to stick with the Dave Line recipe.

Does anyone know if you can just substitute equal amounts of barley syrup with malt extract?
