I have lots of respect for Jamil and love his shows. But we need to understand that in these podcasts he's basically explaining how to make these beers to style to do well in BJCP competitions. The OP can still use the Pilsen light extract and make wonderful beer. Will it be "to style"? Maybe, depends on the judge... Some BJCP judges don't know the difference between an Irish Red and a Flanders Red. If Pilsen is what is laying around and it is a pain or costs too much money to use the English the Pilsen will be just fine.
Is it ideal to use the English? Yes. Is it required? No.
Either way the OP is still making beer.
