   Recipe by: Jo Merrill Place oven rack 1/3rd of way up from bottom of oven;
   preheat to 375 degrees.  Butter a 13x9x2 inch pan and dust all over lightly
   with fine dry bread crumbs; invert pan to shake out excess crumbs.
     Sift together the flour, baking powder and salt; set aside. Melt the
   chocolate in top of double boiler over hot water; set aside.
     Place pineapple in a strainer set over a bowl and let drain.
     In large mixer bowl, cream the butter.  Add vanilla and sugar and beat
   well.  Add eggs one at a time, beating well after each. On low speed, add
   dry ingredients, scraping the bowl with rubber spatula and beating only
   until thoroughly mixed. Remove one cup of the mixture and place in a
   smaller bowl. Stir the lemon rind and drained pineapple into this smaller
   mixture; set aside.
     Add melted chocolate to the mixture in large bowl and beat until very
   well mixed. Stir in the nuts. Spread the chocolate mixture in an even layer
   in prepared pan. Place the pineapple mixture by small spoonsful evenly over
   the chocolate mixture. With back of a spoon, spread the pineapple mixture
   to make a smooth, thin layer. A bit of the chocolate mixture might show
   through--that is ok.
      Bake for 40-45 minutes, reversing the rack postion once to insure even
   browning.  Cake is done when the top springs back when lightly touched and
   cakes begins to pull away from sides of pan.
      Let cake cool in the pan for 15 minutes then cover the pan with a cookie
   sheet and invert.  Remove the pan and cover the cake with a large rack.
   Invert again to cool completely right side up. When completely cool,
   transfer to a cutting board and use long, thin knife to cut into squares or
   bars.
